Does anyone know any 5 minute magic tricks to impress a 6 year old?

Go to http://www.sciplus.com and look through what they have, especially in the category of "Adult and Kids Toys".Lots of interesting things there.Another Item is the Rainbow Disc.It’s a flat reflective Disc about 2" across.Point it at Sunlight coming through a Window and it will cover an entire Wall with an intense Rainbow.You’ve got to see it to believe it.And in a darkened room, aim a laser Pointer at the Disc and it will cover an entire Wall with Laser Dots.Move the Disc just a bit and you’ll have a Laser Light Show for less than $5 ! And there are many other categories with all sorts of Magic Tricks, especially with Magnets.And they ship out super fast, usually in less than a week.Hope this helps !
