Fortune Telling Fish


When you hold a fortune telling fish in your hand, it immediately curls up.



Why???
After allowing your students to 'play' wish their fish for a few minutes, challenge them to figure out how they work. It's a great way to jump start the school year and have the students carrying out the scientific method (without even thinking about it!).

Fortune Telling Fish can be found at novelty stores (they're really expensive there - don't get them there unless you only need one or two or you are in dire need of one NOW), through Oriental Trading Company or here.


PS Everyone's first guess is that they work because of the heat in your hand.... that's not it! See if you can figure it out! If you're really stumped, send me a message and I'll give you a clue.
