Oobleck recipe

Is it a solid or is it a liquid?

1 1/2 cups cornstarch

3/4 cup water

Mix well. It is ready when you can poke it and it is hard, but when you hold it without squeezing it, it is runny.

Gak

1 cup liquid starch

1 cup glue ( all purpose or Elmer's Glue All)

food color optional

Mix well in large bowl.  If mixture is sticky, add a little starch at a time until it is no longer sticky.  If it is stringy, add a little glue until it is a consistent mixture that is not sticky. 

It might take a little doctoring until you get it perfect.  This will mold over time
