I love science. When I was a kid, a large part of my weekends were spent attempting to find the most potent combination of household chemicals. Baking soda and vinegar was too tame for me, and the holy grail of diet coke and mentos hadn’t been discovered yet.
I remember anticipating the arrival of Jeremy’s home chemistry set with ‘bated breath, but the stark reality was deflating. Even in the eighties, namby-pamby, politically correct mail order companies didn’t send sodium and oxidising inorganic compounds to 10 year olds. Spoilsports.
I can imagine if Hotteeze had been around at that time, a number of packs would have been purchased by Team Chemistry Papatoetoe. These heat pads use nothing but chemistry to warm up to a toasty 40 degrees and stay that way for 12 hours. As far as I can tell, it’s a combination of iron powder and potassium chloride, mixed with a couple of inert compounds (carbon and vermiculite) to slow down the reaction.
I was expecting some sort of action to start the reaction, like breaking the cartridge in a glow-stick. Instead, you just open the packet and wait. The reaction with air causes (I imagine) the reaction to start, and within about 15 minutes the pad is warm to the touch. Stick them in your pockets or shoes, and you’ll be toasty. I can imagine they’d be pretty damn nice to have in your ski boots.
When you’re finished, the resulting compound is completely inert, and makes a good soil conditioner for your garden. The outer packet isn’t biodegradable, but Hotteeze say it is “combustible, and does not generate dioxin”, which is OK I guess.
