My kids have been asking to make kaleidoscopes for years—and I mean years! The last time we bought a roll of tinfoil, I thought, “Hmm, let’s give it a try.” They turned out remarkably well—they actually worked! The little guys needed help with the finishing touches, but they would have been just as happy at the halfway mark with something to peer through.
Make three folds (four sections) in your foil-covered cards. Put glue along one side and fold the cards into "triangular tubes." Glue them shut and wait for them to dry. 
drop the other plastic circle on top and let the whole thing dry. Now you have little pockets filled with glitter and sequins.
from the card stock and make a hole through the center with a pencil. Then fold the circle over one end of the tube and tape it on. (We lost patience with waiting for glue to dry—tape to the rescue!).
This is a great, mesmerizing craft that won't get old with your kids!
