 Georgi May 27, 2008 No matter how many times I get ths type of question...I can NEVER get the answer. They are fun to try though...Next time I will get it. friesaregood May 27, 2008 Haha, I did NOT get that one. Awesome answer though. kwelchans May 29, 2008 Here's my solution: A B 0 4 fill B 4 0 fill A from B 4 4 fill B 8 0 fill A from B 8 4 fill B 9 3 fill A from B 0 3 empty A 3 0 fill A from B 3 4 fill B 7 0 fill A from B 7 4 fill B 9 2 fill A from B 0 2 empty A 2 0 fill A from B 2 4 fill B 6 0 fill A from B Considerably longer than the given solution, but still valid. zorro8x Jun 04, 2008 this is my opinion A(9 gallons) B(4 gallons) A B 9 0 5 4 fill B from A 5 0 empty B 1 4 fill B from A 1 0 empty B 0 1 fill B from A 9 1 fill full A 6 4 Fill B rom A and you get exactly 6 gallons in container 9 gallons potato3 Jun 08, 2008 i think there was something like that in one of the Die-Hard movies kunju Jun 15, 2008 great job dragoon9793 Jun 16, 2008 i would just full 4 gallon halfway 3 times, pouring each half into 9 gallon braingle100 Jun 26, 2008 I did it the same way as dragoon and kwelchans zxyggrhyn Aug 23, 2008 I got the sense of the answer but I don't really know what a tap is. Can anyone tell me? HarryPutter Sep 01, 2008 A tap is a faucet... Very nice teaser Shadows Nov 19, 2008 I'd fill the 9 gallon one until it reaches the 6 gallon line. But I got the REAL answer. kwelchans Nov 20, 2008 Shadows, what makes you think there IS a 6-gallon line on the 9-gallon container? Maybe there aren't any lines at all. bluefever101 Dec 30, 2008 this was in die hard 3 and i could never figure it out. very cool/clever.
