Cody from Cody's Lab had 640 pounds of liquid mercury lying around, so he devised an experiment to see if he could stand on it. Read the rest
I love both the idea and the lessons behind this project writer Mike Adamick took on with his daughter during her winter break from kindergarten.
Emmeline wanted to know what life was like underwater for the crabs she and her dad caught in San Francisco Bay. So the two of them brainstormed and figured out a way to answer her question. Together, they built a "crab cam," using an iPhone attached to a crab net.
The results were underwhelming.
But here's the awesome thing. Instead of throwing in the towel, Mike used the experience as a way of showing his daughter was scientific inquiry is really like. Sometimes, your experiments don't work. And, when that happens, you go back to brainstorming, figure out how to improve the experiment, and try again. Because that's the awesome thing about science: Even failure teaches you something.
In the end, Mike and Emmaline were able to improve their experiment, and Mike turned the whole thing into a really sweet and funny video. Great work!
OK, this should make up for the intestinal worm.
In this video, you'll learn how to use an ultraviolet LED to kickstart a chemical reaction capable of sending a cork flying halfway across a lecture hall. It's a hazardous science demonstration! Hooray!
Quick note: The sound quality gets a little sketchy at times. If you click on the CC option in the lower-right corner of the player window you'll be able to read the English subtitles.
