Homemade Silly Putty

Posted by: 

A child favorite around the world--Silly Putty.

I don't think there is a Continent you can go to where kids don't go nuts for the squishy, gooey, blob. It makes children happy with its farting noises and gelatinous mass.

 Adults even have an infatuation with the stuff. 

We took a field trip to our local Discovery Center this week with a 4th and 5th-grade class. 

Students were selected to participate in a number of science experiments. But the silly putty really won the show.

I admit I was pushing my way through crowds of 4th and 5th-graders to get my hands on the freshly made putty.

Students learned about palmers: rubber, plastics and balloons; things that can expand and go back to their original shape. The students learned about molecular reaction and why silly putty works.

Silly putty is so easy and fun you can make it at home or in the classroom with a few simple ingredients:

-White Elmers Glue

-Borax (mix the borax with water before adding to glue)


-Food Coloring

Now part of the fun is that the students were given all the ingredients needed, but not the actual recipe.

The students were required to concoct their own recipe through trial and error.  It was a blast to watch. 

The ratio works out to about 1:4 with the white glue:Borax. Now if  you are up for fun, try letting the students make their own putty with no recipe, just the ingredients.

However, if you are the type who really prefers a recipe, try this one.

This is a great experiment if you are at home for long periods of time. Hooray for Summer and Christmas break!
