Recipies
Original~
put the borax solution into a beaker and with the stirring rod until the borax dissolves. In another beaker, mix together a tablespoon of water and a tablespoon of white glue. Add the borax solution to the beaker with the glue and stir.
Salt~
Mix together the borax solution in a beaker. In the other beaker mix a tablespoon of water and glue. Add 1/2 of a teaspoon of salt to the borax and solution and stir. Add the glue and mix them together.
Cornmeal~
With the borax solution in one beaker, mix together the 1 tablespoon of water and glue in the other beaker. In the beaker with the borax, add a 1/2 teaspoon of cornmeal. Pour the borax solution into the beaker with the glue and mix.
Baking Powder~
Mix together the borax solution in a beaker and 1 tablespoon of water and glue in the other. Add a 1/2 teaspoon of baking powder to the borax solution and mix it into the beaker with the glue. Stir them together.
Sugar~
Mix together the borax solution and 1 tablespoon of water and glue in two separate beakers. In the beaker with the borax, add 1/2 teaspoon of sugar. Pour the borax solution into the water and glue and mix them together.
Variables
