Science in the Tub

While mom and dad are soaking up the Mediterranean air, enjoying sangria and paella in Barcelona, the kids and I are taking in our usual fare of Parmesan noodles and so forth.

Last night John entertained Lucy and me with his science experiment that demonstrated that air exists or something profound like that. He wadded up a big of napkin into the bottom of a plastic cup and then pushed it straight down to the bottom of the tub. When he removed the glass the napkin was ... drum roll please.. dry. It was DRY! That's because there was air inside that got trapped and kept it dry, but if he turned the cup at all you could see the air escape and sure enough... that napkin was WET when he removed the cup.

Unfortunately I didn't stress how important it was to remove the wet napkins and tissues he'd used from the bathwater and so it was full of partially dissolved bits of wet paper by the time John emerged from the bath.
