This is Adin's poster. He tried to make an egg float in water. On the left he drew the regular water, on the right is the salt water. At the bottom he wrote Why? Salt makes it float.
This is Erik's poster. He tried to make an orange float in water. He agreed to ink in his writing so I think you can read it. It floated with the peeling on, and sunk after we peeled it. The tiny dimples in the peeling collect air pockets which is enough to make it float.
The Science Fair is tomorrow. I'm excited. This is our first time doing an experiment for it.
