BUBBLE WRAP JUMP – this is seriously the easiest thing ever. and they LOVED it!! i bought some rolls of the large bubble wrap and placed them on the floor while the kids were out enjoying the activities outside. when they came back in for food and cupcakes it was ready to go! we gave them a count down and then it was a mad house! there may have been a few scared babies (and maybe a kid or two as well lol) but everyone else had a blast!!! simple. easy. awesome.
