Bubbles, cars, and more cars!

Do you know what happens when you blow soap bubbles into a cooler full of liquid and gaseous nitrogen? Neither did we, so we found out. It turns out to be pretty cool.

Totally unrelated: This Saturday (9/29), there’ll be a repeat of the “roadside emergency skills for non-greasemonkeys” class, which we’ve run several times. Change a tire, jump a dead battery, that sort of stuff. Please register if you plan to attend.

Speaking of cars: Our Power Wheels car #3 is going to World Maker Faire in NYC! It happens this weekend, so if you happen to be on the east coast as you read this, come say hi!
