Water Balloon Science

While we were playing with water balloons the other day, I asked C and R how they thought we could make the biggest splash.  I introduced them to the word "hypothesis"; I do not expect them to remember it, but I will bring it up again soon.

Will a water balloon make a bigger splash when dropped on the driveway from a short distance or a greater distance?  C and R both guessed that the balloon dropped from higher up would create a bigger splash.  When I asked them why, R said that it would drop more and C agreed with her.  This science experiment was far from perfect and controlled.  Our balloons were not filled with the same amount of water; I just tried to find two balloons that appeared to be similar in fullness.  We also did not measure the heights from which we dropped the balloon.  This was all just a little bit of fun.

R placed two hula hoops in the driveway.  We dropped one balloon from just a few feet into a hula hoop, and dropped the second balloon into the other hula hoop while standing on a step stool.  They were very happy to discover that they guessed correctly; they were also surprised by how much bigger the splash was from a higher dropping point!

Water Balloon Fun

I cut the bottom off two gallon sized milk containers and covered the edges with red duct tape.  To make the containers look a little fancier, I used the tape to make a C and an R on the containers.  C and R used the containers to catch water balloons.  Well, that was the idea.  They did not even come close to catching any water balloons.  I bet this would be better for children a little older.  Speaking of older children, we did invite T to play, but he was not interested.  Boooooooooooo!!!  C and R had fun though, and so did I!

Don't ask me why R is wearing leggings in eighty degree weather.  She insisted the outfit looked good with her Crocs and she wanted to wear it.  It's all about fashion, I guess.
