Tonight we decided that we wanted to see how the little balls that get larger in water would react when put in other liquids. So we hypothesized that They wouldn't grow in oil. That the oil molecules would be too large to fit though the membrane on the balls. That they would react the same as they always have in water (to absorb the water). We figured that since the corn syrup has some portion of water in it that the balls in this cup would adsorb some water, but not as much the water.
Miles and Daddy counted 10 little balls into each cup.
They sunk to the bottom in the oil and water, but landed right on top of the syrup.
Chris poked them down with a stick.
And then we waited...
The next morning when we woke up this is what we found. They only got bigger in the water. They finally made it to the bottom of the syrup.
Oddly, when we got home from work the balls in the syrup were floating on the top.
The ones in the oil may have shrank... but certainly haven't grown.
It was fun doing an experiment as a family and discussing the results with Miles. I think that if we were to do a second round we might try adding some other liquids like ammonia or vinegar....
