Looking for a printable Valentine’s Day card for your kids? You found it!
I know the first thing that comes to mind with Valentine’s Day is science, right? Anyone…..? Bueller…..? Okay so maybe science and Valentine’s Day aren’t exactly synonymous but they just might be after this little ditty! I’ve been wanting to make a spinning disc illusion toy for some time and then realized we could have some Valentine’s Day fun with it.

My Scientific Valentine: Printable Valentines Cards
- My Scientific Valentine Printable
- Cardstock–Use heavy cardstock so you don’t see the image through the other side
- Hole Punch
- Rubber bands or string
- Step One Print out the front side of the Valentine. Flip over the page and print the backside. Make sure to orient the top of the back page to feed through your printer in the same direction as the front.
- Step Two Write the names of the TO and FROM before cutting the Valentines. Be sure to orient the names in the direction shown otherwise they will be upside down!
- Step Three Cut out the Valentines.
- Step Four Punch a hole at the cross hair marks.
- Step Five Thread a rubber band through one hole and secure. Repeat for other side.
Where’s the Science?
Your brain cannot process rapidly moving images and instead it creates it’s own combination image which is what you see when you spin the disc! It’s also similar you what your brain does with the information it receives from each individual eye, it combines the view from each of your eyes into the image you actually see. Try shutting one eye at a time and looking at a very close object. You’ll notice that the view from each individual eye is different from the view you have of the object with both eyes open. The brain is crazy like that!
M.C. Escher. What kid isn’t fascinated with M.C. Escher and his design work? I used to have several posters of his and would stare at them trying to make sense of what was going on. If you like optical illusions you must check out his work. Escher was heavily influenced by mathematics and geometry and his scenes show impossible constructions. They are a geeky architect’s dream!
Conclusion & More
Did you really think I would let Valentine’s Day pass by without a Valentine’s project that incorporated science? I can’t help myself! This is a really fun little optical illusion your kids can impress their friend’s with.
