It’s a very fun idea for a party! You can make the hats in few minutes. You will need party hats, aluminum foil, scissors, felt, hot glue gun, glue sticks, metallic pipe cleaners and drinking glass. Open up your party hat by pushing the tab on the side of the hat through the slot. Once you open the hat, flatten it as much as possible. Lay the flattened hat on top of some aluminum foil. Cut the foil out in the shape of the hat and cover the hat with the foil. Use hot glue to fix the hat closed! It will look like a metallic hat. The existing strap on the hat should pull right through to the bottom with ease. Make any fun and robotic shape you wish out of your metallic pipe cleaners for the antenna on top of the hat. Cut out robot button shapes from your felt and create a design for each hat!
