Who would have ever thought that a plastic bag, some water, and a few pencils would have adults screaming with fear? Learn how to poke holes in a plastic bag filled with water without spilling a drop. Well, that’s the theory you’re going to test… and it’s wise to practice your liquid trick over the sink. It’s a cool way to learn about the chemistry of polymers. Continue reading
Susanne Åkesson, Professor of Evolutionary Ecology at Lund University in Sweden, has been awarded the prestigious Ig Nobel Prize. The prize, which she shares with six other researchers from Hungary and Spain, was presented to them for their discovery that white horses aren’t particularly bothered by blood-sucking horse-flies. Continue reading
We need water to survive–and Earth is covered in it! Unfortunately, almost all of that water is salty. In this week’s episode of Reactions find out why getting freshwater from ocean water is a lot trickier than you might imagine.
You probably know that voltaic batteries come in all kinds of shapes and sizes, from tiny button batteries to car batteries to huge industrial heavy-weights. They turn chemical energy into the electrical energy that people use to power clocks, toys, cell phones, medical devices, tablets, cars, satellites… and an LED! These batteries seem pretty complicated but you can make a real voltaic battery right in your kitchen. Grab the ice tray and start the electrons moving. Continue reading
We’ve already been told that everybody poops – but did you ever stop to consider why? It’s thanks to our heroic through-gut that humans don’t suffer the same fate as jellyfish and anemones, and every hero has an origin story… Hosted by: Olivia Gordon
Aerogels are the world’s lightest (least dense) solids. They are also excellent thermal insulators and have been used in numerous Mars missions and the Stardust comet particle-return mission. The focus of this video is silica aerogels, though graphene aerogels are now technically the lightest. Continue reading
Futurists predict that those who work in jobs that require lower education and lower skill sets have a higher chance to have their jobs lost or restructured while those that require greater education or are highly skilled will be less affected. There is a growing urgency now because the discussion has moved from the theoretical to the observable. Continue reading
Everyone is self-conscious about having bad breath, but what about acid breath? Our science guy Steve Spangler puts on the lab coat to reveal the chemistry of your breath. Continue reading
