Within an hour of bringing Valentine’s Day balloons home my son asked if we could use them to make our voices sound funny. We told him that we wanted to enjoy the balloons and would breathe the helium after they sunk a bit.
He asked every day after that until we finally talked like the munchkins in The Wizard of Oz.
All it takes is a helium balloon and a straw. Did you ever do it? Make sure you think of something to say before you breathe the helium because it goes away quick.
