Drops On  A Penny Science Experiment

– 2 pennies - water - dropper - dishsoap

Materials Needed:

Using a dropper or pipette, measure how many drops of water a penny will hold before it overflows.

Step 1

In our experiment the penny held 22 drops of water before the surface tension broke and the water overflowed.

Step 2

Now add dishsoap to some water and repeat the experiment.  You will find the soapy water overflows much more quickly.

Step 3

When soap is added to water it lowers the surface tension and breaks up much more quickly.
