Top ten science tricks for parties

// April 12th, 2011 // Comments Off on Top ten science tricks for parties // Just for Fun, Science at Home

Having a party over the Easter break? Add some science with these party tricks. Sure to astound and amaze! My favourite is combining vinegar and bicarb, and pouring the resultant carbon dioxide over candles to extinguish them. I’m doing THAT at my next birthday party for sure, then reigniting candles with the smoke. Oh yes. It’s going to happen.

Gummi bear explosion (and other experiments)

Enjoy what happens when a gummi bear is dropped into potassium chlorate.

Cool. Why did I never do this in chem class when potassium chlorate was available to me?

How does it work, I hear you ask? (And where can I get this stuff?) Potassium chlorate is KClO3, and contains one potassium, one chlorine and three oxygen. It comes as a solid salt, but can be melted by a Bunsen burner.

At high temperatures it decomposes to potassium chloride (KCl) and oxygen gas (O2). No bigger. Until the sacrificial gummi bear.

A gummi bear is full of sweet, delicious sucrose, a source of carbon and energy. Add it in and BAM! The trifectar – fuel, oxygen and heat – the ingredients for fire. The reaction is hugely exothermic, producing MORE heat which produces MORE oxygen which drives the gummi bear into complete annihilation.

For more gummi bear destruction try drowning them, stabbing them shortly after hatching, or decapitating them with a laser.

Curiously, it’s always the red gummi bear that gets it. That’s discrimination.

How moustaches grow

Happy World Beard Day. Yes we have one, and yes it’s today (4th September, add it to your diaries and tattoo it to yer chest.) In honour of this most wonderful of holidays, I present to you the following viewing pleasure.

Okay, I admit it’s not the noble beard, it’s his little brother moose-tarsh. Do beards grow on the same principal? I’m not sure, if anyone is willing to experiment I’d love to see some results.

This picture comes from a fantabulous site called Fake Science which put out many such wonderful scientific pictures. Got time to kill right now? Trying to avoid doing something important? Go check out their tumblr page. I won’t tell.
