This project combines two of my favorite things: crayons and rockets. It may have taken John Coker 12 years to complete this project (hey, who among us hasn’t had a case of lingering works-in-progress?) but the result was more than worth it. He’s even included a step-by-step of how he made the rockets. The detail in matching the Crayola design is pretty impressive. I just want to know if he could find a way to add in that awesome Crayola smell.
Don’t let the elevator music distract you, this system can squirt water at 4 bars, or about 60 psi, as compared to a typical fire hose which packs a working pressure of 100 psi or more. [The] system consists of a number of rotating water jet guns installed on the shipside which provide a continuous […]

Nine enterprising seniors in Yale’s Mechanical Engineering program built this rad spokeless bicycle for their mechanical design class.
That’s “triceratops + helicopter” for the portmanteau-averse. This sculpture, subtitled “Hope for the Obsolescence of War,” was completed in 1977 by the late American sculptor Patricia A. Renick. There’s more pictures over on Gizmodo. [via Geekologie]
Yes, this is a missile. Sorry about that. But it turns out the AIM-9 Sidewinder is the only well-documented example I can find, on the web, of a machine that employs these interesting little widgets called “rollerons.” See the little metal pinwheels at the trailing corners of the fins? The rolleron is basically an air-driven gyroscope, as Tom Harris explains over on How Stuff Works:
