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.

wow. i’ll give it another 3 weeks.
Do we have an update on the status of the mylar balloon? Is it hovering above the carpet?
One balloon is hovering right above the carpet, the other is still going strong. I took this picture a couple days ago.
Wow! Keep us posted on their status. 🙂
