Spangler’s Cornstarch Walk on Water Featured on Discovery’s Time Warp

Time Warp is one of Discovery's newest shows and it's definitely worth watching... even if you're not a science geek. Hosts Jeff Lieberman and Matt Kearney are on the prowl for anything and everything that might be cool to examine under high-speed photography. On the November 5, 2008 episode, Time Warp featured the Cornstarch Walk on Water stunt our team created for the Ellen Show back in February.

It's good to see that our mixing proportions of 2,500 pounds of cornstarch to about 200 gallons of water - all mixed in a cement truck - worked well for them, too. The best part of the segment was the slow motion photography showing just how the non-Newtonian cornstarch and water mixtures behaves under stress. The images are nothing short of amazing. (more...)

Experiment of the Week Travels to Germany

It’s great to get your e-mails and photos of your children and students doing the science activities featured in our Experiment of the Week. These photos are from Sheila Allen, just one of a number of great teachers in the Department of Defense Schools at Ramstein AFB in Germany. Sheila writes... “Well today was the big day and boy did the children have fun! I think my favorite was the Expanding Ivory Soap activity, and I picked just the right kid to trick with the Do Not Open Bottle. We were doing an A-Z countdown to the end of school and so for E we did experiments, and we thought your activities really hit the high point for us! There are 9 kindergarten classes at Ramstein Elementary school (K-2) , and it is a good place for science to happen.” Sheila Allen and her team of mad scientists are a great example of how early childhood teachers are having an incredible impact on the science concepts that young children are being exposed to in the early years of their education. Over the last 15 years, I’ve seen countless examples … (more...)

Cornstarch Walk on Water Stunt - Get a Cement Truck

Mixing 2,500 pounds of cornstarch with the kitchen mixer just didn't work, so we had to find a cement truck... and a very cool cement truck mixing guy. Oh, and you also need three people who know exactly what the cornstarch mixer should feel like when it's perfectly mixed. Jeff, Carly and Renee served as the mixologists while I called the producer at the Ellen Show to let him know that we were ready to roll to the studio. Watch the Cornstarch Water Walk Video

Cornstarch Walk on Water - Get a Really Big Bathtub

The final step is to drive the cement truck filled with 2,500 pounds of cornstarch and 250 gallons of water to the back lot at the Ellen Show and pour the goo into a giant bathtub - 7 feet long, 3 feet wide and 2 feet deep. It's also a good idea to have your oobleck mixing experts change their clothes and spend the next 4 hours mixing the goo by hand to ensure the perfect consistency right before the tub gets moved on stage. How do you move a tub that weighs about 6,000 pounds? Using a forklift, of course. It's also a good idea to find someone in the audience who you've never met and trust that you won't let them sink into a pit of cornstarch goo.

Ellen DeGeneres Wants Giant Smoke Rings!

It's official... I'm flying out to be a guest on the Ellen DeGeneres Show next week. Back in April of 2006 when a producer on the show originally contacted our office, I asked for your suggestions on experiments to do with Ellen. Lots of people suggested my Smoke Rings demo and Ellen might have taken your suggestion (hint, hint). Let's just say that our office was filled with lots of smoke today as someone practiced shooting cups off of everyone's head. We're told that the air date will be next Friday, September 21, 2007. More to come.
