Your Challenge: Stretch your mind and learn chemistry by making Funny Putty!
1/4 cup white glue
1 teaspoon household borax
1 cup water
8 oz paper cup
- Dissolve the borax in the cup of water.
- Pour the glue into the paper cup.
- Add 1/4 cup of the borax water to the glue, and stir really well.
- The glue turns into a blob! Pick it up with your hands, and start kneading it and stretching it.
Take It Further:
Add food dye and glitter to create fun colors for your funny putty!
How It Works:
The borax acts as a cross-linking agent or “connector” for the glue molecules. As the glue molecules become larger, after being linked, they become polymers. Thus, the solution begins to thicken and gel.
- Silly Putty was one of the most popular toys of the 20th century, after it was developed by accident.
- Astronauts in the Apollo 8 mission in 1968 brought silly putty with them to the moon.
- In the 1950s, the Smithsonian Institution added Silly Putty to their exhibits.
- Binney and Smith, the creators of Crayola, bought the rights to the Silly Putty brand in 1977.
- Silly Putty was invented during World War II in New Haven, CT, when trying to find a solution to the rubber shortage.
