Where does the time go?

It's already been over 2 weeks since I posted. So maybe I should just consider myself a radium blogger!

Last week Sam and I made some 'blobber' for science.

It was SO easy to make. It is really cool stuff too. It is almost like silly putty.

Different colors have different stiffness to them so we could see what solution would be better at different activities (bouncing, blowing bubble, etc..)

The yellow was the best for bubble blowing...

I'm sure you're all dying for the recipe, right? In case you didn't see it on my Facebook, I'll post it here too.

1 Tablespoon white glue
1/2 teaspoon borax
1/2 cup water
food coloring (optional)
2 paper/plastic cups

1. Dissolve the borax in the water.
2. pour the white glue into another cup. If you would like, add about 4 drops of food coloring.
3. add 1tablespoon of the borax solution to the glue and stir with a stick or spoon.
4. take the mixture out of the cup and knead it with your hands for several minutes.

Easy peasy. I made double patches. 2 tablespoons of glue then added 2 tablespoons of the water borax mix.

To test the blobber with different solutions try adding different amounts of borax to the water....

red... 1 tsp
blue... 1/2 tsp
yellow... 1/4 tsp

Have fun!
