As you may remember, Julia celebrated her first birthday with a party five weeks ago. As part of the party, we got some Mylar balloons, and about a dozen regular balloons. The regular balloons lost their helium and came crashing back to the ground after just a couple days. However, two Mylar balloons are still floating, attached to a couple end tables in the living room.
So here’s my question: how long do you think these balloons will keep afloat? Leave your guess in the comments.
