As summer heats up, moms are challenged to entertain their school–free tots with activities that will keep them cool and hydrated. It's hard to beat the good old sprinkler in the lawn trick but the $15 Little Tikes Water Ball certainly gives it a run for its money.

While mom or dad inflate the mongo beach ball, the kids can slip on their swimsuits and watershoes preparing for an afternoon of spritzing and slippery wet games. Attach a water hose to the fully blown ball and let the waterworks begin. Parents can determine the height of the fountain sprays by adjusting the water pressure.

Now mom really can sit and relax with her lemonade in the shade.
