Do you do chemistry? If you said no then you would be incorrect. Simply turn the spigot on in your kitchen and chemicals come pouring out of it in the form of water. Warm your dinner in the microwave the radio waves in the microwave speed the water molecules up in the food causing it to rise in temperature.
Do you have Brewdog beers out there in the Colonies? Some of their products come in cans which, rather amusingly, have printed upon them text claiming that they "contain no chemicals".
So to be legally correct it would need to be a empty can with a vacuum inside of it. That could be the next pet rock like fad a empty can with a vacuum of space inside of it. Call it a tad of space.
Cooking is my passion.
I am not fond of cooking, but I can do it since I do enjoy eating.
