Wired Science - News for Your Neurons dopjesactie In samenspraak met het Belgisch Centrum voor Geleidehonden te Tongeren, hebben vrijwilligers een actie opgestart om de vereniging op een ludieke manier te helpen. Dit initiatief bestaat uit de verkoop van ingezamelde plastic dopjes aan een recyclagebedrijf dat er duurzame palletten van maakt. Alleen plastic dopjes van drankflessen komen hiervoor in aanmerking! Vermits het hele dopjesproject meer succes kent dan verwacht, is er een probleem ontstaan qua vervoer. Het BCG heeft enkele vrijwilligers die ervoor zorgen dat de dopjes opgehaald worden bij de verschillende inzamelpunten. Hiervoor zijn ze nog steeds op zoek naar mensen die in de toekomst dopjes willen ophalen. Om meer details over de steunactie te kennen, is de info verdeeld volgens de vragen die je erover kan stellen. Dankzij de solidariteit van velen heeft de dopjesactie dit jaar al 3 450 kg (*) dopjes opgeleverd. (* afgeleverd gewicht per 31/01/2014)! 2013: 273 750 kg 2012: 308 463 kg 2011: 225 241 kg 2010: 254.247 kg 2009: 243.708,5 kg

7 Man-Made Substances that Laugh in the Face of Physics | Cracked.com The universe is full of weird substances like liquid metal and whatever preservative keeps Larry King alive. But mankind isn't happy to accept the weirdness of nature when we can create our own abominations of science that, due to the miracle of technology, spit in nature's face and call it retarded. That's why we came up with... #7. Ferrofluids What do you get when you suspend nanoparticles of iron compounds in a colloidal solution of water, oil and a surfactant? A ferrofluid is a liquid that reacts to magnetic fields in trippy ways that make you think that science is both magical and potentially evil. Tell us that didn't look like the birth of the most sinister dildo ever. What happens is that when a magnetic field is applied to the fluid, the particles of iron compound inside align to it. What the Hell is it Used For? #6. It's not the brick in the picture up there, it's the stuff under the brick. Every once in a while, science rules. #5.
