momstown Oakville has a monthly Little Scientist program and in February we made our own Silly Putty! This activity was such a hit that I wanted to share the recipe as this would be a great March Break activity to do with your kids.
Silly Putty Recipe
-1 cup of white Elmer’s glue (the 225ml bottle)
-3/4 cup warm water.
Mix well, then add some food colouring. About 8-9 drops should do it. If you want darker colours, you could use more.
-1/2 cup warm water
-2 teaspoons of Borax (Borax is a laundry powder booster, and it can be found at the grocery store in the cleaning products aisle)
Once both bowls are well mixed, carefully pour bowl #1 into bowl #2. This is where the fun begins! You can see the coloured glue mixture forming a ball in the water mixture. You can start mixing with a spoon, and then it’s way more fun to use your hands for mixing. You need to really squish it and get all of the glue bubbles out.
Kids love rolling up their sleeves and getting their hands right in the bowl. The mixture starts off very watery, but keep mixing and stretching and squeezing and squishing until the liquid is worked into the putty and becomes dry enough to take out of the bowl. This recipe makes a generous amount – enough for 6 kids to each have their own good sized chunk.
