Explain that for this experiment we are going to do a marble race and drop marbles into each of the liquids.
Liquid marbles experiment.
If you kept all of your marbles and containers clean throughout the experiment and avoided cross contamination of liquids you may be able to store them for regular use.
Now ask them for their hypothesis for which marble will take the longest to sink the bottom.
Ask the kids to each take a marble and hold it over the opening of one of the liquids.
Now it s time to race.
In other words they vanish like magic.
If you want to save and reuse the liquids you use from the activity make sure you thoroughly wash your marbles and drinking glasses with soap and water then dry them completely.
The jelly marbles become invisible due to an identical index of refraction with the liquid.
Liquid marble s progressive deformation determined by increasing compression forces.
In our experiment the marbles took longer to sink when dropped into the jars filled with corn syrup and honey than they did when dropped into the jars filled with water and cooking oil.
As you ll see there s more to this experiment than meets the eye.
The more viscous or thick a liquid is the longer it will take for an object to move through the liquid.
