Take the Magic House. Shrink it. Do the same to the Saint Louis Science Center. Merge the two together and place in a strip mall in Town & Country. Add a few private party rooms and cake of your choosing. Voila! You've got yourself a b-day party that will be the envy of your kid's peer group. And who knows? Perhaps the tykes will even come away a bit smarter and more refined after playing with Myseum's pendulum, air vortex cannon, digital microscope and laser harp. That, or they'll leave breathless from the inflatable trampoline and radar slide that displays the speed of their descent. Either way, you'll be known as the parental brainiac who knows how to plan a hella good time.
