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 Merida - Legende der Highlands 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 sagte its a risk.

My other idea is that Du never sagte theres a ceiling to this room. So if the walls arent to high Du 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

Du 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 Du get 4 quarts, so Du 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..
oder 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 Weiter to the 5 quart and compare them. the difference should be 2 quarts and to get 4 Du cut half of the oben, nach oben off between the 3 quart cup and the 5 quart cup. after Du cut it off, fill it to the oben, nach oben 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 oben, nach oben of the 5 quart cup. it will be 4 quarts then. fill it up and pour it on the bomb.)
