    DIY hydrogen generator

    Seems you really do have to boil it really good to concentrate it. Had a little sample on a spoon and was very viscous. So i torched it for a bit untill it almost stopped bubbling. Put it outside to cool an after there was crystals. I tried to crush one and almost broke the skin. I think i have accomplished this.

    Thanks for all this information :) Im using about 67g of Cream of tartar in about 100ml of tap water. To make my Sodium Carbonate ive used red hot coals and a pie try filled with about a quarter inch of Baking Soda. I stirred it 25 mins in and checked it again at 45 mins which seems it was already done. The texture was more granular. I let it sit on the coals for about 80 mins total just to be safe.

The liquid becomes clear after. After straining the fluid and dumping it back into the container for cooling "fog" started to grow on the container I dumped the hot liquid into. Just waiting for the liquid to cool enough to crystallize. Hopefully i can get one to start growing some.
