Thread: making 'heavy' ice............

I want to make ice that will sink to the bottom of my glass. My first thought was to make deuterium but that will be very expensive.

My next idea was to increase the 'impurities' in the ice so that it is heavier than water - essentially displacing the water that would be ice with something else.........

question is what should I use and in what proportions?

Simply adding a lot of table salt would probably do it, assuming you don't care about your drink tasting terrible.

Also, FYI, it's not a good idea to drink a lot of D2O. Among other things, it can mess with your protein folding, since it doesn't hydrogen bond in exactly the same way as water. Just in case you were actually planning to drink your product...

Drop a ball bearing in each cube in the ice tray before it freezes. Try not to swallow the ball bearings when the ice melts.

It depends on do you want your ice to be homogenic, or you don't care about it...

thanks for the replies!

i'd rather it be cheap and simple, and of course hygenic and not going to affect the taste of the drink............

I was thinking of adding a mineral such as calcuim or something................i don't care too much about it being homogenic, just cheap and simple to make really.

a calcium ball bearing would be good but i don't think I can find those........
