Gifts from the Johnsons

It's hard to know what to say when someone gives your kids one of these....

Marshmellow blow guns. Oh yes, they have been the source of many laughs AND many experiments I might add. Like, what else can I blow out of this thing? Needless to say, we are trying to come up with a gift for the Johnson boys to top this one. Hmmmmm, any ideas? =)
