Bicycle Tutor

I popped my tire (tube) a couple of weeks ago after getting a very thick tube. I just went to the store and got green goo and your suppose to put it in your tire where you put the air so I did and let goo stay in my tire until i put air in. The air does not hold well and I think tube is still messed up.
Any ideas on what to do?

I personally would just get a new tube. In my experience those 'green goo' solutions don't actually work very well.

Hmmmm. I'll have to just use my back up bike for the contest I'm in tomorrow.
