Fingerprint Spiders for Halloween

Did you know that black widows are known for cannibalizing their mates?* Eek. Bet you didn’t plan to come to Tinkerlab today to get info like that.

Fingerprint Spiders for Halloween | Tinkerlab

Spider season has arrived, at least in the Halloween sense of the word, and while it may feel to early for some of us, kids can be wildly in tune with the changing of the seasons. And if it still feels too premature, you can pin this today and keep it up your sleeve for a spooky day down the road.

For us, Halloween catalogues have been arriving for a few weeks now, and decorations are popping up in all the local stores. So when my older daughter started drawing jack-o-lanterns I knew that this project would be a hit.

First let’s talk about supplies…

What You’ll Need

Fingerprint Spiders Supplies

Simple, right?

Step One

Make some fingerprints on your paper.

Have a damp rag handy in case your child is sensitive to having ink on his or her fingers. My kids are okay with this, and understood that that the ink won’t wash off completely until bath time.

Step Two

Draw on spider legs and faces. However you like. Add goggly eyes if you have any handy.

Fingerprint Spiders Making Prints

This is a great opportunity to talk about how many legs a spider has (8), and introduce other fun spider facts (unlike the one I shared at the beginning of this post). Try these:

Spider Facts

  • Spiders are not insects, but arachnids
  • Spiders have 8 legs. Insects have 6 legs.
  • Cobwebs are simply abandoned spider webs.
  • Spiders do not have antennae.
  • In the 1970’s spiders were sent into space to see if they could build a web with zero gravity. The conclusion? While scientists eventually concluded that the quality of the space webs were slightly different from gravity-based webs, webs were made in space!
  • The biggest spider in the world is the Goliath bird eater, a type of tarantula.

Be creative and open-minded.

Despite our conversation about how spiders have eight legs, my independent-minded five-year old gave all of hers eight legs…on both side of their bodies. She said that they look better that way. What do you think?

Step Three

Now that all the materials are out, experiment a little more and be open to new ideas.

We brought out a few more pens to test out the different thicknesses and textures. Then we poured some watercolors into a small bowl and made painted spiders.

From there, the painting and drawing experiments expanded to include abstract patterns and fully covered pieces of paper.

One of my readers and friend, Vlada, sent me these fingerprint spiders made by her daughters. I LOVE the addition of red for the legs. And the goggly eyes! What a fun touch.

Failure is Not Trying

“Failure is only the opportunity to begin again more intelligently.”

– Henry Ford

What do you think about failure? Do you encourage your child to make mistakes? Do you celebrate attempts to try new things? Do you share your own failed attempts freely with your child?

failure is only the opportunity to begin again more intelligently

Last night was Back to School Night at my new kindergartener’s school. The principal gave a motivating talk about the importance of extending the school’s core values into our children’s home lives as a way to reinforce the home-school connection.

At the end of the presentation the principal talked about failure, and how we should encourage our children to work hard to achieve their ideas and goals in spite of their lack of knowledge. If they don’t know how to do something, they shouldn’t see this as a limitation but as an opportunity to fail forward as they learn through the process of trying.

As you can imagine, I LOVED this talk and felt so grateful that my daughter landed in an environment with such entrepreneurial spirit at its heart.

At the end of the talk, they shared a link to an interview with the youngest female self-made billionaire, Sarah Blakely (founder of Spanx), who discussed her journey with ABC News. Whatever you might think of Spanx (I don’t own any myself), you’ll appreciate how her father redefined the word failure for her and her brother. 

“We would sit around the dining room table at night and he would say, ‘OK, kids, what did you fail at today?’ I would say, ‘Dad, I tried out for this sport and I was horrible,’ and he would say ‘way to go,’ and high five me. And it completely reset my definition of failure. So, for my brother and me, failure is not trying.”

Sadly, I can’t embed the video here, but you can watch it here. And if you find her story motivating, here’s a link to Sarah Blakely on YouTube. 

Parents and Teachers as Co-Learners

It’s so important to model our own failures to our children. If children don’t see us struggle as we try new things, and in turn find ways to overcome setbacks, how can we ever expect them to do the same?

When was the last time you celebrated a failure with a child? Not too long ago I baked a new recipe with my kids. We thought we could alter the recipe to use up some of our pantry ingredients and talked about experimentation as we went along. In end the recipe was a disaster, but it was a fantastic opportunity to discuss how we could do it differently next time. Some of the things that came up: follow the recipe more closely, take more time with fewer distractions, and don’t use so much pumpkin.

If you’re interested in this topic, you might enjoy this post on failure.

A question for you:

When was the last time you tried something new? Did you succeed on your first attempt? If not, what did you have to do in order to achieve your goal?

Homemade Card Idea: Peek-a-boo Cards

“Letter writing is the only device for combining solitude with good company.”

– Lord Byron

Do you make time to hand-write letters? I have piles of stationary that I used to adore writing on, but now these delightful pieces of artful ephemera seem to collect a whole lot of dust since everything has become digital.

Card Making: Peek-a-boo Cards | Tinkerlab

I’d love to get back to the fine art of letter writing, but time and energy have taken this once-adored task away from me. Hmmm, I should find a way to get back to it. My kids, on the other hand, will write and make letters for just about anything. No occasion necessary. I’m inspired by this desire to connect with loved ones through their art and words.

Couldn’t we all use a little more connection in our lives?

And that brings me to this…my mother-in-law is a saint on earth.

She’s always putting other people above her own interests and loves my children with all her heart. I’m a lucky one, I know. The other day, this sweet card arrived in the mail from her, and my four-year old couldn’t stop talking about it.

After investigating the mechanics of the card, N wanted to make her own version…as a thank you card for her grandmother’s card. Awwww.

Note to all the grandparents out there: I promise you that the little things you do for your grandchildren do not go unnoticed. Keep on giving of yourselves and the rewards will come back to you.

We talked about how the card had two folds, and the front of it had a cut-out shape. N asked me to help her cut a shape out of the first panel, and thankfully she requested a simple heart.

Maybe you noticed the cute little backwards “N” up there. My daughter has decided that this is how N’s are written, and there’s no changing her mind. She’s strong-minded, and I love that about her.

Fiskar Squeeze Punch

For making cut-outs, you could also use squeeze punches like these. We recently picked up a few of these awesome Fiskars Squeeze Punches at the craft store, and they would be great for making these peek-a-boo cards in bulk. I was first introduced to this tool at my kids’ preschool, and I noticed that most four-year olds can handle them independently. They take a little bit of muscle — too much for my 2.5 year old  and they’re too large for her smaller hands — but older kids love these things!

A few words of love and some more decorations, and then the card is ready for mailing!

With Father’s Day just around the corner, you might want to give this homemade card a go for the amazing dads in your life.

How to Make Paper Airplanes That Go Far

Have you ever made a paper airplane?

Did you learn how to make it from a book? Or maybe it was from the kid you shared a desk with in the third grade?

We tested a few designs, and one of them really stood out as a winner (I’ll share it below). You’ll have to test some, too, and see which one flies the furthest.

This will be fun for the summer! How to Make Paper Airplanes that go Far!

How to Make Paper Airplanes that go Far

Well guess what? Today I’m sharing links to instructions for making paper airplanes that go far and actually work, along with some ideas on how to help kids invent their own paper airplane designs.

So let’s get started with How to Make Paper Airplanes while building Design Skills…

Paper Airplane Supplies

  • A few sets of instructions for making paper airplanes. You can get these from a book or download instructions from the internet (see recommended links below)
  • Copy paper. Thinner paper is easier for children to fold.
  • Markers (optional)
  • Scissors (optional)
  • A clear table

The Best Paper Airplane Designs

paper airplane instructions

Step One: Select a Design

We looked through all of our designs, picked one to start with, and my daughter and I sat down and followed the directions for the first airplane. If you’ve ever made origami, it’s the same approach. Most of the steps were easy enough for her four-year old hands and mind, but I had to help her with a few of the trickier folds.

If you find instructions that are too complicated for you, then skip them and find another plane to make.

Step Two: Teach someone else how to make a plane

Once we got the hang of it, N thought our six-year old neighbor would enjoy this project and we invited him over to join us. Either that or misery loves company.

We each started with another sheet of paper and while we folded, the kids educated each other on hamburger and hot dog folds. If you don’t have a neighbor to teach, teach a parent, babysitter, or grandparent. This step does wonders for building confidence.

Step Three: Iterate and Invent New Planes

Once that first airplane was complete, it was interesting to see where the kids took the project next. My daughter, a designer to the core, got busy decorating her plane with markers. Her friend, a tinkerer at heart who has a soft spot for Legos, began iterating on the design to improve it!

As we folded, he asked me questions like, “On your Eagle, how did you make the wing tips?” And then he proceeded to invent his own series of planes with pointed noses, flat noses, and wing tips.

When my daughter jumped in to help him, I commented that they were iterating. I actually said, “Hey you guys are iterating! Do you know that word? It means that you’re building a lot of planes to test new ideas and in order to figure out how to make it better. Can you say ‘iterate?'” And then of course, they obliged me.

I swear, the teacher thing will probably never leave my soul! Do you ever find yourself in that mode?

Step Four: Take it outdoors

They tested their planes in the house and once they amassed a small fleet of planes, I heard, “Let’s have an airplane show!!” So we took it outdoors to see what the planes could do.

Our friend guessed that the pointy-nosed planes would get more distance and said he was “amazed that the flat-nosed Eagle flew the best.”


All in all, we spent a good hour on this project, and in the end not only did these kids have fun bonding and playing together, but they came away with some new design skills, tools for developing an innovator’s mindset, and good ol’ fine motor skill practice.

Did you ever make paper airplanes as a child? Where did you learn how to make them? And how did they fly?

Inspired by Nature: Four Easy Steps to Follow a Child’s Interests

four easy steps to follow a child's interests

Do you have bees, birds, squirrels, deer, possum, or other creatures milling around your neighborhood?

It’s been wild animal week here at Casa Tinkerlab. We had two big discoveries at our house: a wasp nest in the eaves by our back door and a bird nest tucked into a hole along the siding of our house.

Sad story, we found the bird nest on the ground today, and all of the eggs were gone, probably discovered by a band of squirrels. My two-year old has been keeping a watchful eye on that nest and her first thought went to the mama bird when she said, “I think I hear the mama bird.”

Sure enough, we saw the mama nervously flying around some nearby bushes, and my heart sank for her. We carefully collected the nest and put it back into its spot in the event that the mom can use the nest again.

This wasp nest, on the other hand, was something that I was determined to remove myself. No sad feelings here. Sorry if you’re a wasp fan, but rest assured that no wasps were harmed in the process. Basically, I knocked it down (quite heroically) from it’s post with the end of a broom.

My kids were impressed.

The nice thing about finds like this (as long as no one gets hurt along the way) is the opportunity to learn from them.

Of course my kids had tons of questions about the wasp nest. At first we thought it may have been a growing beehive, so we started to search for information on bees, and then we learned that it was in fact a wasp nest. We also noticed it first came out of our eaves it was round and firm, and that it sank into itself after about half an hour on our dining table.

My four-year old loves to join me in web searches for information, so we started off with searches like “bee hive” and “how do bees build their hives?” The hives looked nothing like our little specimen, but by this point my daughter had an idea and she asked me to collect images of bees and related images that you might find in a garden.

I started a Photoshop file and dragged black and white images to a file, resized them to make them all fit to scale, and then printed the images on her request.  She then spent over an hour carefully coloring in and cutting out her images, and then creating the composition you see here. The only thing that seemed to be missing was a pond, but that’s no big deal when you have a market to fill in the blanks.

Projects like this encourage children to be curious, explore, and tap into their imaginations.


  1. Pay attention to what your child finds interesting in nature
  2. If you’re on a walk or hike, take along an field pack: a backpack to save collected objects, camera, magnifying glass, binoculars, pencil, and a notebook to draw or write in.
  3. Go the library to find books on the topic or search the internet for more information or videos. YouTube is often a great resource for investigations like this. Like this, ahem, educational video on how to remove a wasp nest.
  4. Make something that documents your new-found knowledge. How does your child want to interpret his new knowledge? Maybe it’s drawing, building, cooking, writing a story, talking about it, or taking photos?
