The Velcro Wall (Spiderweb) is great fun for children and adults alike. The wall is 12ft. tall and Fun Source provides 8 suits ranging in sizes from child to adult. Just suit up and jump at the wall off of a mini springboard and stick. The Velcro Wall requires a dedicated 110V, 20amp household outlet. The Velcro Wall requires 1 blower. If you do not have power available, Fun Source rents generators for an additional charge.
