How To Create an Anti-Gravity Experiment
Creating an anti-gravity experiment is a fun way to teach your children about the laws of physics and peak their interest in science. Simply explained, "anti-gravity" occurs when an object is completely free of the force of gravity. It is the complete and total absence of all gravity. You can easily create an anti-gravity experiment at home that will demonstrate what an area devoid of gravity would actually look like.

1
Place the empty glass jar on a table. Press a marble-sized piece of clay firmly down into the bottom of the jar using your thumb. Smash it down all around the inside of the jar, making sure it is stuck tight to the glass.
-
2
Fill the jar halfway with cold water from your kitchen or bathroom tap. Put three to four drops of the red food coloring into the water. Stir the food coloring and water mixture until the water turns a light red.

Insert the straw into the jar, making sure the bottom end of the straw is stuck firmly into the clay. The straw should be standing straight up in the clay with no support.
-
4
Working over a sink, drain all the water out of the jar. Place the jar back on the table.
-
5
Examine the jar for any left-over water. The straw should be half-filled with the colored water. The water molecules are being attracted to each other as a result of the air in the straw forcing the water up. The water did not pour out when you drained the jar, defying gravity.
