Valentine’s Day Thaumatropes for Kids!
Let’s talk about Valentine’s Day with kids. I love Valentine’s Day, and I am trying to teach my kids that it isn’t about just romance. You don’t need a boyfriend or girlfriend to enjoy the day. You can share love with everyone!
Since we are sharing the love with our friends, I thought it would be fun to make some amazing Valentine’s to share. These Valentine’s Day cards are actually really easy to make, but they pack a punch. And they teach a little STEM!
Let’s make some Thaumatrope Valentine’s for kids.
Thaumatrope Valentine’s For Kids
These thaumatropes are really easy to make and are an excellent coloring activity for your kids. You can print them out as is or let your child personalize them to share with others.
Before I get too into the science of how these work, let’s make them.
- Sticks or Straws
- Crayons or Markers
You can make these by hand, but I have included some printables to the end of this post to make these cards even easier for you.
Cut out two squares of the same size. Draw a big heart on one piece of paper. Lightly trace the heart onto the other piece of paper in pencil. (The adult might want to do this, you want to be able to erase it well.)
Draw in the other part of the Valentine. You can add an arrow or just a message like ‘Happy Valentine’s Day!’ Then erase the pencil line.
If you are using the printables then print out the square of Valentine’s and cut out the individual squares. They can be used as is or have your child color them. (The printables have a few blank ones so your child can draw whatever they like if that helps too!)
Place one of the pictures face down and tape or glue your stick to the center of it. (Make sure it is very secure, don’t skimp on the tape!) Take the other piece and place it over the stick, picture facing out. Glue or tape the two pieces together.
The end result should be a stick with pictures facing out on the different sides, ready to twirl.
We used kitchen skewers and they worked really well. We also tried using lollipops so the Valentine would have a sweet treat with it. These worked pretty well, but the sticks were a bit short. This made it hard for Ben to twirl. I recommend getting a lollipop with a long stick for little hands to twirl.
(Safety Note: If you use kitchen skewers like I did you might want to trim the end so they aren’t quite so sharp.)
How To Use Your Thaumatrope:
Hold the stick between your palms and rub your hands together to make the stick spin. Watch the animation happen! You made a thaumatrope!
The Science: How Does a Thaumatrope Work?
What you have made here is an optical illusion. As you can see when you twirl your thaumatrope the images appear to become one picture.
This is known as persistence of vision. Persistence of vision is when the brain takes two or more separate images and views them as one. Basically, the image is switching so fast that the retina is still processing the previous image when the new one appears, so the brain perceives it as one picture.
A prime example of this is the birdcage illusion. One side of the picture has a bird, and the other has the cage. When you spin the two you see the bird in the cage.
History of Thaumatropes
This sort of optical illusion toy has actually been around for a long time. The first thaumatrope was published in Paris in 1825, and there are a lot of optical illusion toys besides this one. Check out this article to learn more: Persistence of Vision
Thaumatrope in Action
I am not the best at getting video of the activities we do, but I did grab a quick one of our thaumatrope examples.
Optical Illusions for Kids
Thaumatrope is really just a big word for a really cool little trick. This is a great way to spark an interest in STEM and share Valentine’s Day fun with your kids.
