This is a great way to explore textures – have the kids find textures to imprint and watch them disappear, or to bounce and watch the balls melt.  Silly putty is great fun!

What you need:

• 1/4 cup warm water
• 1/2 teaspoon Borax

— dissolve the Borax into the water, set aside.

• 1/4 cup cornstarch
• 2-3 ounces of white glue (roughly half a 4 ounce container)
• Food Coloring (liquid kind)

Mix thoroughly.   It will seem clumpy and stringy, but mix for several minuets and it will gain a putty consistency.

This makes 2 small baby food jars worth.  To store, dip the goop in water and place in airtight jar.  Do not eat.  This is “non-toxic” but it is not “good” for you either.  Make sure that the kids are past the “put everything in their mouths” phase before they play with silly putty.
