Our featured experiment:
Rubber chicken bones!
What you need:
1 uncooked chicken bone
1 clean, empty glass jar with a lid
What to do:
Clean the bone thoroughly and let it dry overnight. Put the bone in the jar and pour enough vinegar to completely cover the bone. Put the lid tightly on the jar and leave the jar alone for seven days. After seven days, open the jar and take out the bone.
The bone becomes soft and rubbery. It can be twisted, and, in some cases, tied in a knot.
Why it works:
The vinegar dissolves the calcium from the bone, leaving it soft and bendable. COOL!

What is Alien Hand Syndrome?
Alien hand syndrome (or Dr. Strangelove syndrome) is an unusual neurological disorder in which one of the sufferer's hands seems to take on a life of its own.
AHS is best documented in cases where a person has had the two hemispheres of their brain surgically separated, a procedure sometimes used to relieve the symptoms of extreme cases of epilepsy. It also occurs in some cases after other brain surgery, strokes, or infections. The HAND is after you!
Can laughing too much kill you?
Fatal hilarity is death as a result of laughter. In the third century B.C. the Greek philosopher Chrysippus died of laughter after seeing a donkey eating figs (hey, it wasn't THAT funny).
On 24 March 1975 Alex Mitchell, a 50-year-old bricklayer from King's Lynn, England, literally died laughing while watching an episode of The Goodies. According to his wife, who was a witness, Mitchell was unable to stop laughing whilst watching a sketch in the episode "Kung Fu Kapers" in which Tim Brooke-Taylor, dressed as a kilted Scotsman, used a set of bagpipes to defend himself from a psychopathic black pudding in a demonstration of the Scottish martial art of "Hoots-Toot-ochaye". After twenty-five minutes of continuous laughter Mitchell finally slumped on the sofa and expired from heart failure. His widow later sent the Goodies a letter thanking them for making Mitchell's final moments so pleasant.
