Here's another riddle. It's hard, but that's the point!

Well i dont have a solid answer but i do have some ideas. Ive always been a 메리다와 마법의 숲 guy so i might take a risk and stick the bomb near the door and then get as far away as possible and hope when the bomb goes off its not strong enought to hurt me. But like i said its a risk.

My other idea is that 당신 never said theres a ceiling to this room. So if the walls arent to high 당신 could climb out.

Okay heres my new answer. Id take another risk and use the running water to get the container to 4 quarts. Id do that and just hope for the best haha

당신 fill the 5 quart container with water, then pure the water at the 3 quart container, so in the 5 quart container are left 2 quarts. do that twice and 당신 get 4 quarts, so 당신 SURVIVE!
woooo!!

Fill the 5 quart one.. then from the 5 quart one fill the 3 quart.. u will hav two in the 5 quart one so pour it on the bomb then repeat wat u did... u get 4 quarts on the bomb..
또는 u can just put it under the running water and it will go off after 4 quarts.. then remove it.. lol..

hold the 3 quart 다음 to the 5 quart and compare them. the difference should be 2 quarts and to get 4 당신 cut half of the 상단, 맨 위로 off between the 3 quart cup and the 5 quart cup. after 당신 cut it off, fill it to the 상단, 맨 위로 and pour the water over the bomb. simple. (in other words, put the 3 quart cup up to the 5 quart cup and cut in between the 3 and 상단, 맨 위로 of the 5 quart cup. it will be 4 quarts then. fill it up and pour it on the bomb.)
