Corn is good popped food.
If you’ve been buying microwave popcorn because of the convenience—or a belief that the bag has special popcorn enhancing powers—you’ll want to check out this incredibly inexpensive way to make microwave popcorn at a sixth the cost of commercial bags.The writers at Squawkfox, a frugality-centered blog, were shocked when they did the math on how much they were paying for the convenience of pre-bagged popcorn. When they crunched the numbers they realized they were paying over $3.50 a pound for popcorn versus $0.50 for a raw pound of popcorn. What do you get for the extra three bucks?

How does one breathe new life into a retro-licious toy like Rock ’em Sock ’em Robots? In this day and age, it’s a motion control setup from Zachery Shivers and Anne Flinchbaugh that they created for the TI Design Challenge.The motion controls arrive thanks to a pair of accelerometer-sporting Chronos watches, one per wrist, that interact with some custom circuitry under the ring (not standard back in the 1970s). Physical punches translate into quick jabs inside the ring, with the goal still being “knock your opponent’s head skyward for the win.”

Gimmee More!!!

In this Instructable, talbotron22 shows how to make “Kitty Crack,” an ultra-potent catnip extract containing nepetalactone, catnip’s active ingredient. One pound of catnip yielded 143mg of nepetalactone.

A note about safety. Yes, it is safe to use this extract on cats. I have looked into it, and there are a number of studies (very interesting in their own right) using pure nepetalactone on cats in experiments trying to figure out why it causes them to go bonkers. The upshot is that it’s pretty safe….
