Hi! Welcome to our experiment where we will teach you how to make a rainbow tower demonstrating how density works!
Materials:
Bottlecap
Cherry tomato
Food dye (for coloring water)
Funnel
Honey
Large vase or bottle
Liquid dish soap
Maple syrup
Olive oil
Plastic beads
Popcorn kernels
Rubbing alcohol
Six glasses
Water
Our Results:
Procedure:
Gather materials listed above.
Pour out each liquid into separate glasses.
Use food coloring to dye water (optional).
Arrange the funnel so that the tip is inside the vase’s opening.
Slowly pour each liquid into the vase, in this order: honey, maple syrup, liquid dish soap, water, olive oil, rubbing alcohol.
Gently drop each solid into the vase, in this order: popcorn kernels, cherry tomato, beads, soda cap
Wait for approximately one minute for the layers to even out.
Observe the differences in density!
Safety Considerations:
Do not ingest the materials used for this experiment as they will come into contact with various indigestible liquids such as rubbing alcohol and dish soap.
Check out our video demonstrating this experiment:
science honor society project.mp4How the Science Works:
Density is dependent on how much mass occupies a certain volume. Due to the various density levels between the different liquids and solids, as everything is poured into the vase, there is a layering effect!
