The Cat in the Hat Knows a Lot About That! S01 E26 Termite Towers

When Sally and Nick can't keep their block tower from toppling over, The Cat in the Hat takes them to meet expert tower builders: the termites who, after shrinking down to bug-size, learn from Terry, the termite, how to build a tower that doesn't wiggle (not even wobbling at the same time). However, Raymond, the mole-rat keeps knocking over the termite mound... with some engineering tips from a termite, Sally and Nick can build their block tower higher than before as expected.
