popsci.com — Ice is supposed to float, but with a little heavy water, you can make cubes that sink. You won't want to make much (it costs about $15 a cube), but you can probably make your costs back with the bets you will win.

then you have to ask yourself ... why? My ice that floats cools my liquids just fine. and if i want to eat the ice, i dont have to dig to the bottom of the glass to get it. floating ice ftw.

>>>"If you replace the hydrogen in vegatable oil with duterium, you can sysnthesize "heavy vegatable oil""That's actually not difficult to do. Mix vegetable oil and heavy water and wait. Pretty soon you'll have normal water and heavy vegetable oil. The C-D bond is way stronger than the C-H bond is. You'd have to have the right proportions of each, of course.

Or if you don't feel like endangering your guest's health, try disolving sugar into the water and then freezing that

Deuterium is used in some fusion reactions. And heavy water is often used in nuclear reactors as a neutron moderator<a class="user" href="http://en.wikipedia.org/wiki/Heavy_water#Applications.">http://en.wikipedia.org/wiki/Heavy_water#Applications.</a>

Yes, great idea. "hey I bet i can make an ice cube sink in that shot of isopropyl you're about to do"

I read this at "make ice that STINKS!"

Yeah you and the last half dozen guys who have posted the same damn comment. Its "SINKS" not "STINKS"

Does salt-ice sink too?

i actually did this, i bought some d2o from united nuclear (best place to buy chemicals online in my opinion) and it's pretty cool, it freaks some people out

If I remember right, if you take alot of water and expose that to a wire that has electricity running through it at a high enough voltage, the water will turn into a gas (actually hydrogen and oxygen) and any liquid left is heavy water. A DC adapter might work.I never tried this. I just got this from a documentary called "Hitlers Sunken Secret."It sounds easy. Why is it so expensive? Well, if I was correct, the reason why heavy water is so expensive is because if i remember right only 10% of the water (or much less, 1% or .1% (keep moving the decimal) I misheard) will remain.

I pull something else out time and time again for "science" but it just gets me arrested ....

In theory, there is a cheaper way to make ice that sinks - with regular water too. I think if you put 4 degree celcius water into a mold (maybe an ice tray) and freeze it super fast (liquid nitrogen or something) it should maintain its highest density (.999975 - <a class="user" href="http://antoine.frostburg.edu/chem/senese/javascript/water-density.html).">http://antoine.frostburg.edu/chem/senese/javascript/water-density.html).</a> These "heavy" ice cubes should sink in almost any water for a while. Although after a while, they may float back to the surface because the atoms have enough energy arrange themselves into regular ice structure.Heavy water sounds easier. Although ice cubes made using this fast freezing method would be safe to drink and you could make a lot of them for a cheap price.
