Homemade Lava Lamp

explanation

When oil and water are mixed they form two layer, oil at the top and water at bottom because oil is less dense than water so oil float on water. When you drop seltzer tablet to bottle it goes to water layer and starts to form bubbles by chemical reaction. These bubbles go up taking some colored water with them. At the top of the bottle air escapes and leaves the water behind which falls back down. Doing so it creates nice effect of lava lamp which you enjoy.

Make your own Flubber at home

Have you watched Flubber movie 1997? If yes, then you know that in this movie Robin William makes a green rubber like substance named “Flubber”. In this experiment we will make flubber (It won’t talk! SORRY!) But you can play with it and see what science is behind it.

Required Materials

  • Warm Water
  • 1 cups of Elmer White Glue
  • 2 tablespoons of Borax
  • Green Food Coloring
  • Air tight bag

how-to-make

  1. Pour ¾ cup of warm water and 1 cup of white glue in a bowl. Add 2 to 3 drops of food coloring in the bowl and stir the mixture with spoon thoroughly.
  2. Pour ½ cup of warm water in another bowl and add 2 tablespoons of borax in it. Stir the solution to completely mix the borax in water.
  3. Pour all the solution of borax in the first bowl and stir the mixture thoroughly with spoon.
  4. Pour all content of bowl in an air tight bag. Close the bag tightly and make sure no liquid is leaking from the bag.
  5. Knead the mixture in the bag with your hands from outside for 5 to 10 minutes.

Your flubber is ready. You can remove it the bag and play with it. If your flubber is sticky then let dry a little bit then it will be okay.

explanation

The flubber you made is a Polymer, you made by mixing borax and glue together. Borax               acts as connector (crosslinking agent) for the glue molecules. When glue molecules joined together and formed larger molecule chain, you got a gel like substance.
