EXPERIMENT @ HOME

Here are some of the experiments we featured on Fox 21/27′s So Cool Science School that you can do at home!

Make Your Own Slime

Materials:

  • Elmer’s Glue® (8 oz bottle of Elmer’s Glue-All)
  • Borax (a powdered soap found in the grocery store)
  • Large mixing bowl
  • Plastic cup (8 oz size works well)
  • Spoon
  • Measuring cup
  • Food coloring (optional)
  • Water
  • Paper towel for clean ups
  • Zipper-lock bag

 Directions:

  1. Empty the entire bottle of glue into a mixing bowl. Fill the empty bottle with warm water and shake. Pour the glue-water mixture into the mixing bowl and use the spoon to mix well.
  2. Add a drop or two of food coloring (optional).
  3. Measure 1/2 cup of warm water into the plastic cup and add a teaspoon of Borax powder to the water. Stir the solution – don’t worry if all of the powder dissolves. This Borax solution is the secret linking agent that causes the Elmer’s Glue molecules to turn into slime.
  4. While stirring the glue in the mixing bowl, slowly add a little of the Borax solution. Immediately you’ll feel the long strands of molecules starting to connect. It’s time to abandon the spoon and use your hands to do the serious mixing. Keep adding the Borax solution to the glue mixture (don’t stop mixing) until you get a perfect batch of Elmer’s slime. You might like your slime more stringy while others like firm slime.
  5. When you’re finished playing with your Elmer’s slime, seal it up in a zipper-lock bag for safe keeping.

 

Make a Snowflake

Find out how crystals are formed using borax and a few other household ingredients.

Materials:

  • String
  • A wide-mouth jar
  • Pipe cleaners
  • Boiling water
  • Borax
  • A pencil
  • Blue food coloring (optional)

Instructions:

  1. Cut a pipe cleaner into three sections of the same size and twist the sections together in the center. Make sure the points of your shape are even by trimming them to the same length.
  2. Attach a piece of string and tie the opposite end of the string to the pencil. You will use this to hang your completed snowflake.
  3. Carefully fill the jar with boiling water. For each cup of water add three tablespoons of borax. Add one tablespoon at a time and stir until the mixture is dissolved. Don’t worry if some of the borax settles at the base of the jar.
  4. Add food coloring if you’d like to give your snowflake a nice bluish tinge.
  5. Put the pipe cleaner shape into the jar so that the pencil is resting on the edge of the jar and the pipe cleaner shape is sitting freely in the borax solution.

Leave the “snowflake” overnight and in the morning you will find the snowflake covered in crystals!
