When subjects are asked to watch a movie and not display emotions (say, a comedy without laughing, or a tearjerker without crying), they evidently use up glucose in particular areas of their brain in a way that subjects who are free to react however they want do not.

Believe it or not, an ammo box can still be of use to you once its rounds are gone. You can use it for storage, as a toolbox, or possibly even as a Faraday cage. But if you want to use it as more than just a container, why not turn it into a portable set of speakers that you can take with you anywhere? The ammo can speaker pictured above was made by Instructables user Dustin White. He started with an empty .50 cal box, though you could probably even use thinner 5.56 or 7.62 mm cans. He remove...

This video shows roller furling of a jib in 5 knots of wind. Mild tensing is kept on the jib's sheet to enable the jib to warp tightly around the headstay. In high wind conditions, this is best done in a deep running reach. The mainsail will tend to shield the jib from the wind. This will prevent excess luffing of the sail and make furling easier. In a pinch, you can always let the jib out, by loosening it's sheet and roll in the jib, but in high winds excess luffing may occur and this can da...
