How do you work out how safe or dangerous a chemical or some other substance is? This week's Risk Bites takes a look at chemical safety, and estimating health risk from chemical exposure. This week's Risk Bites team: David Faulkner (post-production) Andrew Maynard (all the other stuff) Risk Bite
Fluorescein is an amazing substance that when added to water or alcohol will become UV reactive and make some of the coolest effects you have ever seen. Which test is your favorite? *Hang with me* Facebook: http://facebook.com/HackThePlanet Twitter: http://twitter.com/householdhacker Serious Bus
How do you know if the chemicals in the stuff you use and eat are safe? Only a small fraction of the thousands of chemicals in use today have been thoroughly tested for safety. Part of the problem is that how we test chemicals now is slow, expensive, and relies an awful lot on animal testing. How
Penny boards are small, light and super handy. I travel by the train often, so I like to take a penny board with me to get faster from A to B. Especially during the winter being faster is pretty dangerous on the sidewalks, because it gets dark much sooner, so because of that I bought a LED-Pennyboar

Large stars die, and then explode into massive supernovae. This scatters all the elements of the periodic table throughout the Universe, which results in the third threshold of complexity -- the creation of chemical elements. Website: https://www.bighistoryproject.com/portal Facebook: https://www.f
The three types of a chemical reaction (analysis, synthesis and conversion) are only presented theoretically! An application and chemical experiments for this take place in the attendance phase at school! Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done b
