I'm in a bubble

I'm in a bubble that started out big. It was a big bubble that rolled and bounced along the pavement and through this bubble I could smell the flowers. They didn't always survive the rain but I could smell them. Now I find that my bubble has shrunk a bit and is starting to stick to my ears and get in my hair. I have a sneaky suspicion that it has something to do with that sharp rock I rolled over. I think the sharp rock put a hole in my bubble and it started leaking. The check tire pressure light came on but quite frankly I didn't do anything about it. Now it's all non-round and floopy. I need to make me another bubble. I need to reset it.

Where's my reset bubble button?
