Slime! (or silly putty)

Oh, yeah, another cool thingy made out of Borax.

You need:

- 1 Tbsp of Borax (where do you get Borax, you ask? The laundry aisle)
- water
- clear school glue (or regular school glue)
- food coloring *
- glitter *

* optional, but added fun

Ok, I don't have exact measurements because I couldn't find exact measurements anywhere.

Borax (sodium borate - Na2B4O7)
But you need to dissolve the 1 Tablespoon of Borax into 1 Cup of water and set that aside.

Then pour probably half a regular sized bottle of glue into a bowl. Add water (not a ton) to that glue and stir it together.

Clear glue makes see-through-ish slime and the regular glue makes more of a pastel color.

Add the food coloring and/or glitter in this step, if you choose to do so.

And now for the FUN part!

Pour in the water/Borax mixture and begin stirring it together. It'll get really goopy and stringy (the polymers doing their thing) and then knead it together with your hands. (I suppose you could let the kids help)

The more you knead it, the less gooey it will be. It will eventually turn into a lump of almost rubber-like material. If you prefer it to be 'slimey',  you can add more water. My boys play with it until it dries out a bit and then add it to a bowl of water and it gets all stringy again. (Then I take a slotted spoon and spoon it back into a zip-lock baggie)

Store it in an airtight container or you no longer have 'slime.'

Yes, it will wash out of clothes. BUT, I highly suggest playing with this in a room that doesn't have carpet!
