>#5: Flubber

>Get ready for some fun! Making and playing with flubber is one of my favourite things to do.

Here are the supplies you’ll need to make flubber:
Borax (also called sodium borate and can be found in the cleaning aisle in stores)
Warm water
White glue
Container (an ice cream bucket is good)
Measuring cup and measuring spoon

Pour 10 mL (2 tsp) of Borax and 250 mL (1 cup) of warm water into your container. Add white glue. Stir it well. Let it sit for a minute and then mix it again with your hands.

The glue turns into flubber, so the more glue you add, the more flubber you will make. Make sure you mix the glue really well–the Borax mix is what makes it ungluey. If you want a ball of flubber, form it when you take the flubber out of the water. As the flubber dries out, it becomes more firm and harder to shape–and bouncier!

Have fun!

This activity promotes math skills (when children are allowed to assist in measuring) as well as allows for safe, fun experimentation. Chemistry is fun!

Playtime is more fun when it's shared with others. Share this post with your friends.
