Penny lab reasalts

In the penny lab you had to estemat how meny drops of water a penny could hold.
I estemated about 4 drops.
The second thing to do was to see really how meny apnny drops of water a penny could hold.
When I tested my thery on if a penny could only hold 4 deops of water.
My thery was not right for the penny held more then 4 drops of water, it held 5 to 6 drops of water.
