MEL Science Pop It: Make 2 frames from thick cardboard: cut out the same pattern of round holes in each one. Prepare a piece of foamiran for each hole. Glue them all to one of the frames and glue the second frame on top. Use a hairdryer to shape the bumps: heat each membrane and use an egg to mold it into the right shape. Your Pop It is ready! Try to craft a keychain this way!
Сandy tray Pop It: Draw an outline of a frame on thick cardboard to fit a candy tray. Cut the frame out and glue the candy tray to it. Now you can pop it!
An elastic bubble has two stable positions. If you apply too little force to the dome, it will return to its original position when released, since it is closer to it. By increasing the pressure and pushing the dome closer to its second stable position, you make this latter position more comfortable for it and force it to make the switch. The membrane jumps abruptly to the second position and stops, creating a pressure drop – a sound wave.
