Two different effects for children's magic, stage and parlor magic. 

Kaleidoscopic Tube: In this effect, two cardboard tubes are shown on all sides. After placing one tube inside the other, the magician reaches inside and pulls out a long, flowing streamer from the tubes. The effect can be repeated with different colored streamers. 

Mental Balloon: A simple rope, a colored blown-up balloon. That's it. The magician is able to pop the balloon with mind power. No glue, no needle, no magnet, no thread. Everything can be examined, before and after. A real baffler!
