Now it s time to race.
Liquid marbles experiment.
In other words they vanish like magic.
Liquid marble s progressive deformation determined by increasing compression forces.
Ask the kids to each take a marble and hold it over the opening of one of the liquids.
As you ll see there s more to this experiment than meets the eye.
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.
Repeat the experiment up to this step starting from preparing the graduated cylinder to measure the viscosity of each liquid for each of the remaining test liquids.
The experiment demonstrated that liquid marbles elasticity gained through the liquid meniscus formed between the shell s particles allows a compression up to 30 from the drop s initial dimension.
Explain that for this experiment we are going to do a marble race and drop marbles into each of the liquids.
Now ask them for their hypothesis for which marble will take the longest to sink the bottom.
The jelly marbles become invisible due to an identical index of refraction with the liquid.
It is assumed that liquid marbles.
