 The nephews point out a balloon floating near Gladstone, who doesn't want to make the effort of lifting his arm to get it, saying that either a bird will pop the balloon for him or it simply doesn't have the winning ticket.Eventually, Donald seems to have caught all the balloons, which, as he points out, must have been placed together via a thermal inversion, meaning they must be floating above a place with a low temperature.The place happens to be the Money Bin.
