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 メリダとおそろしの森 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 発言しました its a risk.

My other idea is that あなた never 発言しました theres a ceiling to this room. So if the walls arent to high あなた 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

あなた 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 あなた get 4 quarts, so あなた 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..
または 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 次 to the 5 quart and compare them. the difference should be 2 quarts and to get 4 あなた cut half of the 上, ページのトップへ off between the 3 quart cup and the 5 quart cup. after あなた cut it off, fill it to the 上, ページのトップへ 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 上, ページのトップへ of the 5 quart cup. it will be 4 quarts then. fill it up and pour it on the bomb.)
