Goo, Goo, Glorious Goo!

Tuesday, August 7, 2007


B-10 and CW finished all their schoolwork early today, so we did a family science experiment tonight and made Goo!

B-10 decided to go with green goo, while CW went with blue. The adults got the leftovers from each bowl - which was plenty! It's easy to make, a blast to play with, and easy to clean up after you're done with the experiment.

Let it be known that goo makes excellent passing gas noises. ;)

The coolest thing about goo is that when you are moving it slowly, it acts like dough - very squishy and holds together. But if you move it quickly it acts kind of like bread, and breaks with jagged lines. We observed what happens when you leave goo alone in a big pile (it slowly spreads out) and when we pushed down on it (it gets a dull finish and takes our handprint, before spreading out and becoming shiny with no handprint).

I purchased three small Ziploc containers to hold our goo and keep it fresh. A wonderful Science moment all around!

Goo Recipe:

1 Cup All-Purpose White Glue

1 Cup Water (divided by 3/4 Cup and 1/4 Cup)

Food Coloring

1 Tablespoon Borax

Blend glue and 3/4 cup water in a large bowl. Stir until very smooth. Add food coloring until desired color. Set this bowl aside.

Blend 1/4 cup water with borax in a small bowl. Stir until dissolved. (This works best if you use very hot water.)

Add contents of small bowl to large bowl; stirl until goo begins to form. Then remove goo from bowl. There will be liquid remaining in the bottom of the bowl. (You can add more borax/water mixture to this liquid and make even more goo!)

Notes: Use METAL spoons to stir! Store in airtight containers. Do not let children ingest borax!

Have Fun Gooing!
