From Simreal
I had a nominal presence at Maker Faire 2008. We did two fun things -- the Abyssal Organ, a novel pipe organ made from PVC pipes and making use of beat frequencies; and Slime! Slime is fun.

Slime!
The basic slime recipe is very simple.
First, create a 4% mixture of PVA (weight over weight, so for 1 gallon of water which weighs about 3,787 grams, add about 152 grams of PVA powder and then heat and stir until it is dissolved, but no hotter than about 195ºF). Create a 1% mixture of methylcellulose (38 grams to a gallon). Create a 4% mixture of Borax.
Now, for normal slime I use 20 parts PVA with 20 parts methylcellulose. The PVA gives it body, the cellulose gives it better flow and stringing characteristics, and some stickyness. To this, I add about 1 part of the borax solution. Note that the borax solution continues to tighten the slime for about an hour, and more still when the slime is handled.
If you want your slime to be really slippery, make a 1% solution of xanthan gum (easier said than done), and then use 20 parts PVA, 10 parts methylcellulose, and 10 parts xanthan, plus 1 part or so borax to tie it all together.
All of these components (except xanthan gum) can be purchased at The Chemistry Store at reasonable prices. Xanthan gum can be found at grocery or health stores.
