Magicool works simply because when you spray it on yourself, the ether evaporates out of the spray very quickly, rapidly cooling the water droplets before they hit you, in the process. There's no mystery to it
I wonder how many innocent rabbits, guinea pigs and monkeys had to endure hours of spraying into the eyes, ears, wounds and mouth to test the safety of that!
The toxicity of the substances contained in the product are likely to have been long known before it was formulated. They're not exactly new. It's mostly water.
If people want to magically cool themselves they should wear a hat and buy an ice-cream.
If you think that virtually anything you eat, ice cream included, has not had every additive exhaustively tested on animals then you are frankly a bit gullable. Even when a product says it has not been tested on animals, it does not imply that the components that went into making it have never been tested.
On the subject of atoms and all that: why, with particle accelerators and all this, is it still beyond science to turn lead into gold?
It isn't. In theory, you could carefully build up gold atoms from lighter ones by heavy particle bombardment, or by carefully chipping down heavier ones.
In practise it's not possible simply because of the energy required, the fact that you are probably more likely to shatter your target nuclei than get it to fuse with the incoming one, that it would take interim stages of likely highly unstable nuclei that would just decay again faster than you can get from one metastable stage to another and that the end product would likely contain an infinesimal amount of gold relative to the now probably highly radioactive side products.
We've already grown diamonds, built steam engines a few molecules across and set off multi-megaton nuclear bombs...
Growing crystals isn't that difficult, although getting them pure is another matter. Conceptually, nuclear devices aren't that complex either. Nanotechnology on the other hand...
And back to soft drinks - what is an emulsifier, what is acesulfame, how does a 'widget' work in beer cans and just who sells/regulates the E numbers?
Answers on a postcard!
Well, an emulsifier is simply any substance that allows you to mix two normally immiscable liquids, eg hydrophillic and hydrophobic. You'll find them in all sorts of things from ice cream to moisturising cream...
