Naked Egg – Sick Science! #031
This experiment answers the age-old question, “Which came first, the rubber egg or the rubber chicken?” It’s easy to make a rubber egg if you understand the chemistry of removing the eggshell with vinegar. What you’re left with is a totally embarrassed naked egg and a cool piece of science.

Burning Money – Sick Science! #030
It’s probably not a wise idea to soak a $20 bill in a flammable liquid and set it on fire, but that’s what you’ll have to do with this science demonstration. Sure, you could use just a $1 bill, but then you don’t sweat as much. There is a point to all of this burning… it’s the fact that to everyone’s amazement, paper money never actually burns (if you do it correctly). Read on to discover the secret behind this amazing demonstration.

The Power of Air – Sick Science! #029
We’ve taught you the water absorbing secret behind the polymer inside diapers, but did you know that a Diaper Genie bag is a great way to demonstrate some properties of air? That’s right! That plastic smell-shield isn’t just for odor defense any longer. Now you can use the thin plastic bag to show Bernoulli’s Principle and amaze your friends.

Expedition 27 Crew Prepares for Launch as their Soyuz Rocket Move to Launch Pad
The Soyuz TMA-21 spacecraft and its booster and were moved to the launch pad at the Baikonur Cosmodrome in Kazakhstan on a railcar April 2 for final preparations before launch April 5, Baiknour time, to the International Space Station. The Soyuz will carry Expedition 27 Soyuz Commander Alexander Samokutyaev, NASA Flight Engineer Ron Garan and Russian Flight Engineer Andrey Borisenko to the complex. The trio will spend six months on the station, joining station Commander Dmitry Kondratyev, NASA Flight Engineer Cady Coleman and European Space Agency Flight Engineer Paolo Nespoli, who have been in orbit since December 2010. Samokutyaev, Garan and Borisenko are in final training for launch with their backups, Anatoly Ivanishin, Dan Burbank and Anton Shkaplerov. The footage includes interviews with Astronaut Nicole Stott, STS-133 Mission Specialist, and with Mike Lopez-Alegria, Deputy Director for ISS, NASA Flight Crew Operations.

Hovering Plane – Sick Science! #027
We don’t know if the Wright Brothers ever made the attempt, but Steve Spangler has defied the odds to create a hovering airplane. We don’t suggest any passengers (because they wouldn’t fit), but this Floating Paper Plane is a great hands-on science tool for teaching the science behind airplanes, lift and drag, and principles of air.

Shuttle’s Boosters Recovered in HD
NASA has released the first ever up-close, high-definition video of Kennedy Space Center’s solid rocket booster (SRB) recovery ships retrieving SRB segments from the Atlantic Ocean following a space shuttle launch. The unprecedented video is from the launch of the most recent shuttle mission, STS-133, Discovery’s final flight, on Feb. 24.
Following each space shuttle launch, crew members of Liberty Star and Freedom Star pull the spent boosters out of the ocean and return them to Hangar AF at Cape Canaveral Air Force Station in Florida. Once they are processed, the boosters are transported to Utah, where they are refurbished and stored, if needed. -
NASA’S MESSENGER Spacecraft Begins Historic Orbit of Mercury
NASA’s MErcury Surface, Space ENvironment, Geochemistry, and Ranging, or MESSENGER spacecraft successfully achieved orbit around Mercury at approximately 9 p.m. EDT Thursday. This marks the first time a spacecraft has accomplished this engineering and scientific milestone at our solar system’s innermost planet. Shown is reaction in MESSENGER mission control at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md., as engineers received telemetry data confirming orbit insertion, plus animated depiction of the event. Among other goals, MESSENGER is expected to detect whether ice exists at Mercury’s poles.

NASA’s MESSENGER to Become First Spacecraft to Orbit Mercury
After more than a dozen laps through the inner solar system, NASA’s MESSENGER spacecraft will move into orbit around Mercury on March 17, 2011. The durable spacecraft — carrying seven science instruments and fortified against the blistering environs near the sun — will be the first to orbit the innermost planet. At 8:45 p.m. EDT, MESSENGER — having pointed its largest thruster very close to the direction of travel — will fire that thruster for nearly 14 minutes, with other thrusters firing for an additional minute, slowing the spacecraft by 862 meters per second (1,929 mph). The orbit insertion will place the spacecraft into a 12 hour orbit about Mercury with a 200 kilometer (124 mile) minimum altitude. At the time of orbit insertion, MESSENGER will be 46.14 million kilometers (28.67 million miles) from the sun and 155.06 million kilometers (96.35 million miles) from Earth. MESSENGER has been on a 6.6 year mission to become the first spacecraft to orbit Mercury. The spacecraft followed a path through the inner solar system, including one flyby of Earth, two flybys of Venus, and three flybys of Mercury. This impressive journey is returning the first new spacecraft data from Mercury since the Mariner 10 mission over 30 years ago.

Flying Tea Rocket – Sick Science! #024
The 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 teachers and kids used to make Ditto paper “rockets.” Since Ditto paper is a thing of the past, science enthusiasts have found a simple replacement – a tea bag.

Marble Gravitron – Sick Science! #023
Last summer, Spangler Labs took a company trip to an amusement park. We didn’t go for a company retreat, we didn’t even go on a day off. We went to do research on physics, the science of motion. One amusement park ride that really got Steve thinking was the gravitron. As we all stood in a circular room with our backs against the wall, the walls began to spin. Faster and faster the walls spun until the floor dropped out from under us. There were shrieks of terror as everyone thought they were about to fall, but to our surpise… we didn’t drop! Steve wanted to find a way to recreate this phenomenon on a small, kitchen-science scale. Steve Spangler Science gives you the Marble Gravitron!

Candle Seesaw – Sick Science! #021
Recently, the scientists at Spangler Labs had a day where they recollected their fond memories of elementary school. Some thought back to their favorite science or math class, but Steve was excited about the playground equipment. He loved the monkey bars, the swings, and even loved to play tetherball.
But, he recalled, his favorite thing to do on the playground was seesaw. Steve’s memories even included a daredevil stunt where he seesawed while it was on fire. He was a regular elementary Evil Knievel. And then it hit him…what if he could use some amazing science principles to make a magic seesaw?

NASA’s Kepler Finds Its First “Goldilocks” Candidates
NASA’s Kepler Mission has discovered 54 planet candidates that orbit in the habitable zone of their host star; this so-called “Goldilocks” region is “not too hot or too cold, but just right” for the possible existence of liquid water on the surface of a planet. Four of those candidates are near Earth-sized planets in orbit around small, cool stars. The findings, discussed at a news conference held Feb. 2 at NASA Headquarters in Washington, are based on data collected by the space telescope between May and September, 2009. Ground-based observatories will be used this spring and summer to help determine if these candidates can be validated as planets.

Color Changing Carnations – Sick Science! #020
Where does the water go when a plant is watered? With this experiment, children can discover for themselves how essential the functions of roots and stems are to plant growth. As the colored water is absorbed, students will be able to see how the water is absorbed into the plant and the petals of the carnation change color.
