Overinflated green balloon

As voluminousNano has requested me to do, I overinflated one of the balloons to about 135 cm (~53") from it's original 45" in 4 inflations. The top of the bookshelf (on the left) is exactly 135 cm away from the top of the couch.
And if anybody is still interested in getting those balloons for yourself, check my journal entry, where I tried to answer every question about these: jdegriz.deviantart.com/journal…
I know that I was probably late with my journal entry, but it wasn't something that I could done faster considering that some pretty bad stuff happened to me (not related to balloons in any way).
