We shot watermelons, cinderblocks, starting fluid, and a bunch more. Its a long video, but totally worth staying till the end because you get to see me choke on a bug haha.

The first test was shooting bullets at a watermelon. We shot Sodium, Potassium, and a special alloy of sodium & potassium thats a liquid! Its basically the closest thing to shooting mercury out of a gun!
These bullets are insane!

For this video I bought 150g of potassium for $325 , and 500g of sodium for $150. Each bullet holds 1g of metal. I also had to buy regular .45 hollowpoint ammo to modify ~.50c/bullet. At these prices, each potassium bullet costs $2.50 Each sodium bullet cost .80c. The liquid alloy is 25% sodium, 75% potassium.


These bullets must be stored under dried and degassed solvent, blanketed in a dry, and inert atmosphere. Storing the bullets in regular oil or other hydrocarbon solvent will quickly destroy the entire bullet and casing in less than a week. Common oils and solvents are slightly permeable to oxygen and moisture which will react with the alkali metals to form corrosive hydroxides which will etch the zinc in the brass casing. Oil will enter the casing and inactivate the smokeless powder. After 1 week 1/10 of the bullets stored under oil did not fire.\n
