Learn the basics of thermodynamics with a film can cannon.
Butane from a lighter provides the fuel, the lighter’s sparker provides the ignition, and the film can provides the ammo, so all you need it some time and a few simple tools to build your very own.
Ever wonder why time seems to slow down during moments of danger?
According to David Eagleman, a scientist at Baylor College of Medicine in Houston:
When a person is scared, a brain area called the amygdala becomes more active, laying down an extra set of memories that go along with those normally taken care of by other parts of the brain.
“In this way, frightening events are associated with richer and denser memories,” Eagleman explained. “And the more memory you have of an event, the longer you believe it took.”
Eagleman added this illusion “is related to the phenomenon that time seems to speed up as you grow older. When you’re a child, you lay down rich memories for all your experiences; when you’re older, you’ve seen it all before and lay down fewer memories. Therefore, when a child looks back at the end of a summer, it seems to have lasted forever; adults think it zoomed by.”
How did he test this theory?
Researchers dropped volunteers from great heights. Scientists had volunteers dive backward with no ropes attached, into a special net that helped break their fall. They reached 70 mph during the roughly three-second, 150-foot drop.
“It’s the scariest thing I have ever done,” said David. “I knew it was perfectly safe, and I also knew that it would be the perfect way to make people feel as though an event took much longer than it actually did.”
Indeed, volunteers estimated their own fall lasted about a third longer than dives they saw other volunteers take.
Though science is responsible for many of the greatest discoveries ever made, it’s not always so serious.
Oddee put together a list of the 10 Most Bizarre Scientific Papers, and despite the topic of study, each was a serious paper, conducted by serious scientists with serious tests and serious results.

In what must have been one of the most difficult and most painstaking research projects of all time, a cosmetic surgeon spent hours studying photos of topless models to determine the perfect pair.
Apparently, his findings indicate that the perfect chest isn’t about size. Instead, it’s all about proportion.
“The ideal is a 45 to 55 percent proportion – that is the nipple sits not at the half-way mark down the breast, but at about 45 percent from the top.”
So who came out on top?
Lingerie model Caprice Bourret, who apparently has the best of the breast.
And the worst?
It’s a sad day for Victoria Beckham, who apparently has “unnaturally round” mounds.
I can only imagine what this experience must feel like:
Jennifer Sutton, a 23-year-old Londoner, received a heart transplant after her old one said ‘no more’, and she then put that old heart on display at an exhibition in London.
“Seeing my heart for the first time is an emotional and surreal experience. It caused me so much pain and turmoil when it was inside me. Seeing it sitting here is extremely bizarre and very strange. Finally I can see this odd looking lump of muscle that has given me so much upset. It’s tremendous it has become an object of fascination and will get people thinking about the disease, heart transplants and organ donation.”
I guess she really can wear her heart on her sleeve.
Tripwire is an interesting solution to the problem of too much noise coming from your local airport.
Designed by the MIT Media Lab, these coconuts were hung from trees around the San Jose International Airport, and then any time one detected noise above the allowed level, it made a call to the complaint hotline and left a pre-recorded complaint. They even stored the data for later analysis.
