Complete random here......BUT

I need to know if its possible to make an EGG burn ?????

Don't ask why - its " i bet an egg can burn" vs " i bet it won't" type thing.

Answers on a post card.


So far, ive considered making Kno3/egg meringue - but it'll take forever to dry out....

i guess drying it out might work.... an egg is roughly 100 cals if that helps.

i remember seeing a video involving a chemical that oxidised just about everything it touched..it was a liquid....its name escapes me.

Could this bet the answer......anyone got experience with manganese heptoxide ??

could you nitrate the egg? could be interesting lol

are you wanting to make the egg combust as a fuel or just burn. because you could just inject a flammable liquid like petrol into the egg until its saturated

need it to burn as a fuel.

Came from the argument about theory of calories

Mainly 1 calorie = unit of energy needed to raise 1kg of water by 1C at 1 BAR
1kg water=1 litre
water boils at 100c

1 egg contains 100 Cals....

So the theory was there is enough energy in an egg to boil a litre of water. Now, we all know that its not going to work....But someone suggested it was impossible for an egg to combust.

I guess it might need to get pretty hot to burn.

You'd have to account for the mass of H2O in the egg! That has to boil then evaporate so there is the latent heat of evaporation to remove from the useable heat.

KMnO4 is pyrogolic with some organic liquids but whether the water content would prevent flammability...............

Pierce the shell. Dip it in liquid oxygen and light it.

There's a classic demo sometimes done with Jelly Babies. Melt a couple of grams of potassium chlorate in a pyrex boiling tube over a Bunsen and drop a Jelly Baby in. You very quickly see just how much energy they contain! This might work with boiled egg as well.

If you're looking to measure the calorific content you need a setup called a 'Bomb Calorimeter'. It's basically a sealed pressure vessel containing the sample and a nichrome ignition coil in an oxygen atmosphere. This is submerged in an insulated water bath with a thermometer.

The coil is energised, igniting the sample and the temperature rise of the water bath measured. The excess pressure can then be vented. Allowing for electrical energy input, the combustion of the fuse, the residue and the various heat capacities involved you can gain an accurate calorific value.

Who needs chemicals when we have a microwave :P just stick that bad boy in the microwave for approximately 1 hour and you should have a lovely egg covered microwave by the end of it that may have if your lucky burnt at the same time, jobs a good one. Now on a serious note isn't egg shell just Calcium AKA phosphoric acid can dissolve it so I heard so would be interesting to see if it produced any sort of colour lol.
fireworks is my aim setting of is the game

vinegar will dissolve it overnight.

In fact, if you guys are ever bored - put an egg in a cup with 1/2 vinegar, 1/2 water - leave it for a day or two, and drain the water. what you get left with is a complete egg, in a sack - no shell......its see-through......

Anyhow, back to this thing. last night i mixed an egg with 40g of Pot. Nitrate - and dried it at 50 degrees. What im left with now, is a dry egg, under a layer of Nitrate Crystals. FAIL !!!

Next option.

could you dissolve the egg in a solvent mix in chosen Oxidizer and once the solvent evaporates it will be completely mixed.

well i'll be damned.

i though that the white powder formed on top was Pot Nitrate...and it is....i weighed it - and it was only 13g - meaning 27g of nitrate was dry, IN the egg mixture.

It DOES BURN - you have to get it pretty hot, but it does go, and leaves some residue, presumibly that from the fat of the yolk.

On that note, it'd work better if i removed the yolk - as the "dried" subject is the kinda like leather, dry, but flexible rather than brittle.


FANTASTIC, stand by for a youtube video of a burning egg.
