Here's something fun to make with the kids. Its easy and fun, and a bit scientific.
The ingredients, Elmer's Glue, liquid starch and food coloring.
Pour 1 c Elmer's glue into a bowl, then mix in the food coloring.
Pour in 1 c liquid starch and start stirring.
This is where it gets fun, when the two mix, they start to get thick.
Pretty soon it turns stretchy.
Violet is looking a little bit concerned.
After a bit more stirring, it all comes together into a solid mass. It is sort of stretchy, sort of gooey and lots of fun.
A few notes:
If it seems too sticky, mix in more starch.
It does stick to clothes and the carpet. Don't worry, it comes out easily in the wash or with warm water and a bit of rubbing. You might want to keep it on a tray or in the kitchen. Wren stuck a glob on his head once, AHH! I just stuck him in the bath and it pretty much dissolved with warm water and a wash cloth.
Not all glue is equal. Elmer's is the best, and glue you get from school supply stores works. But the glue I bought at the dollar store did not work!
Gak should last for a month or so if kept in a tight container.
