How could someone be brutal enough to even bite something as cute as this? =D


...

BOOOOOOOM!



Who did this?!


23 April 2011
Another ordinary day... but.. EXTRAORDINARY to us!
The chemistry lab was again morbid since the making of smoke grenades months ago..

So... let's watch this trailer and in few seconds u will know the most brutal way to kill a gummy bear.





Therefore, to start off, what we basically need is simple:
1. A gummy bear (the one you hate most)
2. Potassium chlorate (salt formula: KClO3)
3. A set of retort stand, clamp, Bunsen burner and a lighter
4. A Pyrex combustion tube
5. And it is advised to do these precautions, just in case: a pair of gloves, and a pair of goggles
6. A pair of tongs
7. Forceps
8. Last but not least, for visualization purpose, get some table salt (sodium chloride or potassium chloride)!

Alright, to kill a gummy bear without regrets, here's the procedure... *smirk*
I. Gently place some potassium chlorate salt into a dry combustion tube (2-3 spatulas would suffice); it's better with a Pyrex combustion tube, just in case.
II. Clamp the combustion tube in a 45 degree slant position onto a retort stand, make sure it's tightly and stably clamped.
III. Now, light up the Bunsen burner (with a lighter, of course), and make sure you open the air hole to switch the flame blue, so that it burns hotter.
IV. Place the Bunsen burner right below the combustion tube and the heating starts.
V. As the potassium chlorate in the combustion tube takes its time to melt, start getting a gummy bear to stand by its queue of death~ Now, you may spread some NaCl or KCl evenly over the gummy bear so as to produce colored flame (yellow-orange in our case).
VI. After the potassium chlorate completely melts, meaning that now you've already obtained a solution of pure molten potassium chlorate, kindly use a pair of forceps, pick a gummy bear, and put it inside the tube. (Before that, you would like to switch the lights off!)
VII. See what happens. Enjoy! =)

Some fine remarks over here.
First, as soon as the poor gummy bear touches the molten KClO3, things start to get real messy. Depending on the concentration of sugar in the bear itself and the amount of potassium chlorate you use, this experiment will present you with approximately 1 minute of astonishment. Now, let's discuss why this happens..
See, a gummy bear is made of sugar (like you don't know), mainly, sucrose. And potassium chlorate, in its molten form, is a very very very strong oxidizing agent. Basically, this experiment is just an oxidation reaction, but so strong that you will be able to observe vigorous flames and even explosions within the small and narrow reaction vessel -- the combustion tube.

So, what creates light and smoke in that abrasive manner with just a teddy and a pile of salts?
First, let's have a look at the reaction:

C12H22O11(s) + KCLO3(l) --> CO2(g) + H20(g) + KCL(g)
Sucrose + molten Potassium Chlorate --> Carbon Dioxide + Water Vapor + Potassium Chloride gas

What actually gives out the light that you observe? Well, due to the narrow space of the reacting vessel and the strength of KClO3, the energy produced in this reaction is so strong that only heat energy being produced could barely sustain the energy traffic which is, indeed, tremendous. And according to the Principle of Conservation of Energy, energy cannot be destroyed or created, but can be converted from one form to another. Thus, in this case, energy is so strong and vigorous that part of the energy released is converted into light energy, in spite of just heat energy which can be observed in the form of steam.


Alright, that's about it! But, one last thing: before commencing this experiment, be very sure that the ventilation is good, because there will be a lot of CO2 and KCl gases rushing out.

Let's KILL! =)
