Effect would be more than 5 stars if possible.There is a sw**ch .Sitting down is easy.Standing will require more effort since there is basically a very 3 dimensional object.Its if Lloyd Barnes got a job at Tenyo.Also-does NOBODY own a hole punch anymore.Who spends 5 minutes cutting circles out?I may be too honest,but it could be a decent quick trick to get people attention before more tricks that are professional built like JUMP.I would do it but not very often.I will video tape the crap out of it before I break it cause I may not make it twice.
