To make slime to add to your own alien table following here~
First in one bowl dump a bottle of school glue. (we used a 4oz bottle.) then fill it with warm water and dump that in to. Add some green food coloring and mix well.
In another bowl mix about half cup of water with teaspoon of borax.
Once both are mixed well slowly pour the borax water into the glue water and mix.
Mix till slime forms.
The pink and green ufo's are from Busy Bee Toys (fab store for all different things)
We also added a black light for more effect but was not really needed.
Slime is not edible and should never be given to a kid who might try to eat it, play at our own risk.
My kids are almost 4 and 5, both play great and never have tried to eat any.
