Buoyancy

"I'm studying buoyancy!!" Olivia beamed and dashed back into the bathroom.  She kept showing me things she was going to test for their buoyancy and then went back in.  Here you see some of her experiments.

In other news, the other day the kids made a kite.  I'm afraid it never flew, and I talked to them about some things that would improve it (stronger material, instead of pieces of paper taped together, and a lighter string (they had rope).  The colored side was beautiful, though.  They'll get it.
