Root beer, that is. I mean, that’s science, right? Delicious, creamy science? (Now I want a root beer float. It’s 6:00 in the morning. I have issues.)

Today’s deal over at Sellout.Woot is a Mr. Root Beer bundle of the original kit plus a refill package for just $12.99 plus $5 shipping (and remember, Woot now gives you an entire day of shipping across all their sites for that one $5 fee). For reference, the kit alone goes for $22 at Amazon, while the refill pack costs another $10. So even after shipping, it’s a pretty awesome deal. Together the kit and the refill will yield four gallons of root beer. That is a lot of floats.

Plus you can turn it into a learning thing for the kids, then drink all their root beer. Win/win, right? Right.
