"I maintain there is much more wonder in science
than in pseudoscience. And in addition, to
whatever measure this term has any meaning,
science has the additional virtue, and it is not an
inconsiderable one, of being true."
-Carl Sagan, 1934-1966
The children in your afterschool program may enjoy this easy, hands-on science project for
making a plastic-like liquid/solid substance called "Gluep" from the Science is Fun in the
Lab of Shakhashiri website .
You will need 1 teaspoon of laundry borax, 1 tablespoon of white glue, food coloring, two
cups, a spoon and water. In one of the cups, dissolve 1 teaspoon of borax in 5 tablespoons
of water. You will need to stir this for some time for it to dissolve (a small portion of the
borax may not dissolve). In the other cup, combine 1 tablespoon of water and 1 tablespoon
of white glue. Add food coloring if desired and stir this mixture with a clean spoon until
uniform. Put 2 teaspoons of the borax solution from the first cup into the glue mixture in the
second cup and stir. The mixture will stiffen into a soft lump. After the lump has formed,
take it from the cup and knead it for a couple of minutes. This is Gluep.
Have children experiment with their Gluep by rolling it into a ball and then letting the ball
rest to watch and see what happens. They can also try dropping the ball onto a tabletop or
rolling the Gluep into a cylinder and pulling the ends slowly or quickly. Have children record
their observations and create other experiments with their Gluep to examine its elasticity.
Store Gluep in an air-tight plastic bag.
