Our Study on WW2

22 Feb

Today we were working on our WW2 study (we use Tapestry of Grace), and one of the interesting things we learned is that Silly Putty was discovered by accident.  “During World War II, Japan invaded numerous rubber-producing countries, cutting the United States off from the rubber supplies it needed to manufacture truck tires and boots.  So the War Production Board asked American companies to develop a synthetic rubber.  James Wright, a General Electric engineer, invented a gooey, bouncy substance when he combined boric acid and silicone oil in a test tube.  Wright didn’t see a use for it, but marketing whiz Peter Hodgson thought it would make a great toy.  He was right.  When Hodgson introduced it to American kids in 1949 it was an instant hit.  In 2000, Silly Putty celebrated its 50th year of popularity and it was inducted into the National Toy Hall of Fame.” Great World War II Projects

Our boys have loved learning about World War II and anytime we can do some hands on projects, it’s even better!  So, today we decided to make some Silly Putty.  It turned out pretty good-but take heart it is messy!

What You’ll Need

2 cups Elmer’s all-purpose glue

1 cup liquid starch

large ziplock bag (but I would use a bowl next time)

food coloring

1. Pour the glue and starch into the bowl and mix it well.

2. Once it’s mixed well, add the food coloring.  (This was enough to make two batches)

3. To keep it from drying out, put it in a ziplock bag when you’re not playing with it.
