sink. Even non-scientists find great joy in dropping stuff in water
to see if it floats or sinks. Fans of David Letterman are quick to
point out one of Dave's favorite segments called "Will It
Float?" Here's the latest float or sink challenge: Why do
lemons float in water but limes sink? Think you know the answer?
Not so quick...</p>

Vista, Colorado asked this question: Would you voluntarily run at a
full sprint headfirst into a brick wall? Now, think of sitting on a
bicycle without a helmet, and then tip over with a little over a
second to intervene before your bare head hits the ground. Which
sounds worse? This question and his amazing research lead Raleigh
Burt to win the 2005 Junior Division Best Individual Science
Project for the State of Colorado. Despite the fact that bicycle
helmets are considered the single best means of protecting cyclists
from the leading causes of head injuries and death, many people
still choose not to wear a helmet. That is the choice many riders
make to become one of the 67,000 cyclists who will suffer a head
injury this year.</p>

If you've ever seen seen an ice skater start to spin slowly on the tip of their skate and then speed up into an incredible blur of a spin, the secret is pure science. The best part is that you don't have to be on the ice to test out the science behind the spin. Find an office chair that spins easily and a few weights and you're ready to make yourself dizzy sick. But it's all in the name of science.</p>Mon, 01 Mar 2010 14:52:35 -0700Ice Skating Spinhttp://www.stevespanglerscience.com/experiment/ice-skating-spinLeprechaun Secrets Revealedhttp://www.stevespanglerscience.com/experiment/leprechauns-st-patrickshttp://www.stevespanglerscience.com/content/science-video/leprechaun-secrets-revealedThe mysteries of Leprechauns have been discovered!Color the water green & build a leprechaun trap for St. Patrick's Day<p>This is not your ordinary experiment... but parents might call it a social science experiment. Remember, it doesn't take a laboratory to get children to wonder, discover and explore. Sometimes it just takes a little creativity and a passion for making learning fun. Just imagine what your kids would do if the water from your faucet came out green. Those darn Leprechauns are at it again.</p>

of air poking down from the clouds. But this tornado-like effect is
not limited to just the air. A fire tornado or fire whirl is just
like a tornado but it's made of fire. As the heated air from
the fire rises, strong air currents (often whipping through the
trees) cause the air molecules to spin (often referred to as
angular or rotational momentum) which shapes the flame into the
shape of a tornado.</p>

But what if you could a make a giant bubble over 1 meter (3 ft) tall? Once you know the secret behind these super bubbles, you can amaze your audience by surrounding them in a human-sized bubble!</p>Mon, 25 Jan 2010 15:57:49 -0700How to Make Super Bubble Solutionhttp://www.stevespanglerscience.com/experiment/giant-bubble-experimentBalancing Nailshttp://www.stevespanglerscience.com/experiment/00000083http://www.stevespanglerscience.com/content/science-video/balancing-nailsCan you balance eleven huge nails on the head of one nail?Balance all of the nails on the head of a single nail.<p>The object of the challenge is to balance all of the nails on the head of a single nail. All of the nails have to be balanced at the same time and cannot touch anything but the top of the nail that is stuck in the base. If you're really ambitious, you can try your luck at our large-scale version using landscape nails and a friend as the base. Enough of this idle chatter... get balancing!</p>Mon, 18 Jan 2010 20:14:00 -0700Balancing Nailshttp://www.stevespanglerscience.com/experiment/00000083Tea Bag Rocket - Convection Currentshttp://www.stevespanglerscience.com/experiment/tea-bag-rockethttp://www.stevespanglerscience.com/content/science-video/tea-bag-rocket-convection-currentsThe science of hot air and convectionA great after dinner science stunt using a tea bag and matchesThe Tea Bag Rocket is really an adaptation of a classic science demonstration called the Ditto Paper Rocket. If you're old enough to have experienced Ditto paper, you'll recall the bluish-purple ink and that unforgettable smell of freshly printed copies. (Come to find out... both the Ditto machine solvent and the ink were highly toxic, but no one seemed to care back then.) Each piece of Ditto paper had a sheet of tissue paper that separated the two-part form, and it was this discarded piece of paper that kids used to make the "rocket." Since Ditto paper is a thing of the past, science teachers found a simple replacement - a tea bag.
