Hundreds and hundreds of you vied for the chance to win a SmartLab kit for maximum hands-on fun. And thank goodness, because my own children keep slinking into my office and regarding the boxes with longing. I’m ready to send ’em off to the lucky winners and cement my position as Meanest Mother Ever. (Um, send off the boxes, not the children. I may be mean, but I’m still rather fond of the kids.)

319 entries, 4 winners: Not the greatest odds in the world, I’ll grant you. But these four lucky Want Not readers are about to be a whole lot nerdier happier. Here are our winners:

• Jen R (commenter 142) wins the Custom Motorcycle Studio
• Jane (commenter 50) wins the Blast-Off Rocket Racer
• Kyallee (commenter 66) wins the You-Build-It RoboXplorer
• and Chuson (commenter 193) wins the Extreme Secret Formula Lab.

Congratulations to our winners! (Winners, please check your email!) This was a fun batch of toys and I hope everyone enjoys them.

Many thanks to all who played, and special thanks to the folks at SmartLab and their helpers at Goodman Media for the generous prize donations.

Didn’t win this time? Don’t be sad! I still love you! And I have plenty more goodies to give away, too, so stick around for more chances to win.
