At-Home Lab: Making Bread
YouthExperimentsFoodScience...Learn a little about at-home chemistry in the kitchen.
How do bulletproof vests work? - Max G. Levy
AdultsConstructionScienceChemistry...Explore the chemistry behind what makes kevlar so strong, and how this essential synthetic fiber was invented.
Why Don't Oil And Water Mix?
YouthExperimentsHow-toScience...Join recipe tester Adelina as she uncovers the scientific secret to making water and oil mix.
Flame Rainbow
YouthExperimentsScienceChemistry...The rainbow flame chemistry demonstration, is one of the most colourful displays of chemistry known to humankind.
Why Water Dissolves (Almost) Everything
AdultsEducationEnvironmentScience...Water can dissolve more substances than anything else on earth...so why doesn't it dissolve everything away?
What is entropy? - Jeff Phillips
AdultsPhysicsScienceChemistryThere's a concept that's crucial to chemistry and physics. It helps explain why physical processes go one way and not the other: why ice melts, why cream spreads in coffee, why air leaks out of a punctured tire. It's entropy, and it's notoriously difficult to wrap our heads around. Jeff Phillips gives a crash course on entropy.
The chemistry of cookies
AdultsFoodScienceCooking...You stick cookie dough into an oven, and magically, you get a plate of warm, gooey cookies. Except it's not magic; it's science. Stephanie Warren explains via basic chemistry principles how the dough spreads out, at what temperature we can kill salmonella, and why that intoxicating smell wafting from your oven indicates that the cookies are ready for eating.
Sulfur Hexafluoride Gas
AdultsScienceTechnologyChemistry...A model boat floating on sulfur hexafluoride (gas significantly denser than air) at the Physikshow of the University of Bonn!
Incredible Chemical Reaction!
AdultsPhysicsScienceChemistry...This is a classic chemical reaction. It's called the iodine clock reaction. There are several variations of how this chemical reaction can be performed using different chemicals than the ones I used in the video. You can order clock reaction kits from several science related websites. You can also use simple store bought chemicals like vitamin C, iodine, hydrogen peroxide and starch. A quick internet search will turn up multiple ways of performing the experiment.
How do they do artificial diamonds?
AdultsBusinessScienceTechnology...Gemesis diamonds are mostly yellow due to the Nitrogen in the atmosphere getting inside the crystal during the growing process. Apollo diamonds can be created in all colors including colorless depending on how much impurity is introduced in the growing chamber. e.g. add boron to make blue diamonds.
