Hamster balls can be done almost anywhere there is an open, level grassy area such as a park* or back yard. Indoor parties can be done at a school or recreation room. A dual-lane criss-cross race that intersects in the middle introducing a potential collision between contestants. This track can be used dry or add water to the four pools for added excitement.
