What to do when it is Hot, Humid, and Stormy?

Why, play Pirate Legos, sharks and Barbies in the never used bath tub. After school today both boys rushed to do their homework. They have been asking for awhile to put their Lego boats in the bath. Today was very hot and very stormy, lots of wind and torrential downpours, so no walk or outdoor activities. They played in there for an hour, ate dinner, and are now back in there playing. At this point I think they will be playing in there until bedtime. All 4 are having so much fun but it is so loud. That room just echos with little voices singing "Yo Ho Yo Ho" and "Da Dun, Da Dun, Da Dun".
