- keep some tape nearby.
my kids love doing science activities. they really enjoy the solar bag. we tried it last year at our house, but it was very difficult to find enough space to run and fill it. also there were lots of trees and obstacles and we ended up tearing it very badly on the chimney. we still had a lot of fun. this year we bought another and took it to the local park. very fun! we did get a couple of holes that we taped, but i think we will able to use it again.
bought one several years ago for a summer science camp and loved it!
