There is one big deal i must say about the filling process. The best way to do it is to make icecubes from the water that we mesured and throw them 1st in to tank, then you mix the citric acid and bakeing soda well and dump it into the tank. This way the dry ingredients are well mixed and thanks to that they will disolve better in water when it melts. You don't have undisolved lumps on bottom.🎉😅 Chears!
Easy, you add 300 ml of ice cubes, they must fit the bottle so measure the bottle neck and search online for- water bottle ice cube tray - (the capacity is not important, you can keep additional ice cubes frozen) then you mix 84 gr of baking soda and 194 gr of citric acid. Get the ice cubes in, add the mixed powders and that's it. You can use ridiculous black gloves too.
