This one takes advantage of rising heat to spin the paper. Be careful when doing this experiment. The paper could catch fire.

Another oldie but a goodie. The tighter you make the lines, the bigger the hole it will create.
#4 Annoying Noise Maker
This one is super easy and really annoying
#5 Ruler Breaker
Using nothing but a piece of paper to "hold" down the ruler, you can break it.
#6 Möbius strip
If you take a strip of paper, twist it half way and tape the ends, then cut down the middle, the 2 pieces of paper will join and make 1 large loop If you take the ends and twist them a full time and tape them together then cut down the middle, it will create 2 linked loops.
#7 Impossible Fold
This trick has some controversy. Some say you can't fold more than 7 times, more than 8, or more. It also depends on the thickness of the paper and the make up of the paper. Generally though, it's extremely difficult, if not impossible to fold ordinary sheets of paper more than 8 times.
This one is very impressive. Be sure to use just a little layer of water. You can make different sizes and shapes of flowers. Some times they will bloom fast and other times slow.
#9 Paper Popper
This one is super fun, because you can create it almost anywhere. It takes a little practice. You want to make sure to seal off all of the holes in your hand and when you "clap" your hands together you're trying to create a nice air pocket that forces the paper out. If you get really good, you can create extremely loud pops.
#10 Super Paper Strength Template: http://imgur.com/WQbwbyI
The "tighter" you can make these the stronger it will be. Obviously you could cut thinner strips and have 10, 15, separate cylinders but to me, the taller and fewer the cylinders the more impressive it looks. I calculated that with the 6 cylinders I had, it could hold at least 150 pounds. Be careful when trying this trick.
