5 Blank Circles
3 Emoji Circles
1 Pack of Crayons
10 Glue Dots
14 Foam Adhesives
Make your Emoji Thaumatropes
Color the tears of the laughing emoji blue, the tongue of the winking emoji red, and the heart of the kissing emoji red.
Color 3 of the blank circles yellow.
Use a glue dot to stick a straw onto the back of one of the emojis. Make sure the straw does not stick up over the top of the emoji.
Stick another glue dot on the side of the tip of the straw that is opposite the emoji so it is centered over the first glue dot.
Place 3 foam adhesives on the back of the emoji circle in step 3. The foam adhesives should be placed so there is one to the left, right, and top of the tip of the straw.
Stick the yellow circle on top of the emoji circle on the second glue dot, making sure the yellow side is facing away from the straw. Make sure this circle is centered over the emoji circle.
Place the straw in between your hands and spin the straw rapidly. When you look at the emoji, the yellow circle and the white face of the emoji should blend together so the face of your emoji looks yellow instead of white!
Repeat steps 3-7 with the other two emojis!
How it works
Make your helicopter
Thaumatropes are toys that are made from discs with different pictures on each side. If the pictures are rotated quickly, they seem to join together to make one! This happens because the human eye can only see 10 to 12 images per second. As a result, the human brain combines the two separate, alternating images into one visual image. This is called “persistence of vision.”
Create your own thaumatrope using two blank circles. Draw different pictures on each circle and follow steps 3-7! Try to make drawings that complement each other or “go together.”
