Make a trebuchet (mostly) out of lego, capable of launching small objects like acorns or minature marshmallows over thirty feet. It’s a geeky ABS cousin to the PVC Marshmallow shooter, and you can build one yourself.

Evil new year: Turn your Champagne into a DEADLY weapon!!!!
We’ve had some complaints lately about Evil Mad Scientist Laboratories not being sufficiently evil. (Too many projects that are “safe” and “legal.” Blah blah blah.)
Today we’re going to fix that by helping you to turn your New Year’s Champagne into a DEADLY weapon!!!!
(Just in case you were wondering: Yes, four exclamation marks are required.)

What do you call this thing?

The “business end” of a Stegosaur’s tail has a name. Do you know what it is?
Apparently, it’s called a Thagomizer.

The Evil Mad Science Auxiliary Flickr Group
We’ve started a flickr group called the “Evil Mad Science Auxiliary,” it’s located at http://www.flickr.com/groups/evilmadscience/.
The purpose of this group is to provide a place to show off your pictures of things that are (at least marginally) related to projects on our blog. Did you build a cylon-o-lantern? Some interesting Lego creations? Some LED Holiday decorations or build one of our kits? Post it in the group and let us see!

There are many reasons to take your music with you. The usual solution requires headphones. But sometimes you need to bring your party– and your speakers– along with you. We used to pull a giant stereo trailer along with us on social bike rides, and some of our friends still do (movie). But when it’s just you and a couple of buddies, and there’s ice on the ground, you don’t want to be towing 50 lbs of stereo around behind a bicycle. Granted, the speakers I used are nigh unto worthless and the amp eats batteries like candy, but they made just enough sound for our little group. I needed a small padded bag for them, though, so I made one.
