In your race to get outside and play this morning (finally, it’s May!), you failed to notice one important detail: the rain.

If spring showers have you (and your kids) running in circles, it can’t hurt to add a couple more offenders to the mix: Rubbabu Torino racers. Made from natural foam and covered in a velvetlike material, the soft hot rod wheelies ricochet off walls and furniture without leaving so much as a scratch.

The Torino racing set includes two cars and a racetrack play mat (with markers) to facilitate the action. However, once our kids turned the corner, there was no stopping them down the hardwood straightaway of the hall.

Until we waved the checkered flag.
