Foam bricks, aluminum foil, black marker, pens or something to poke small holes in the foil, black pipe cleaners
This is a fun party activity. Purchase foam bricks from a craft store and cut them into walkie talkie sized rectangles (about 12x2). Cut large pieces of foil and give two to each child to cover the foam. Have the kids poke small holes (a pen tip works great) in the foil on the top and bottom for the ear and mouthpiece speakers. Then with a marker, they can draw numbers for a keypad. Have the child put a small black pipe cleaner in the top for the antenna. The kids can then pretend to talk on their walkie talkies. Great for Army-themed parties or Power Ranger parties.
