It swells relatively quickly with the inflator (5 minutes). The ribbon is pretty simple to use so as not to inflate the bubble. A 90 cm it is not super swollen as I could read it.
As against it is susceptible to puncture. If you have any fences with soft focus iron son not to play too close. We, we popped a tomato support! The bubble has not exploded it just deflates slowly allowing the children to continue to play with for 20 minutes.
Anyway very good game but I'm not sure the reusable side.
