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.

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

I got the sense of the answer but I don't really know what a tap is.

Can anyone tell me?

A tap is a faucet...

Very nice teaser

I'd fill the 9 gallon one until it reaches the 6 gallon line. But I got the REAL answer.

Shadows, what makes you think there IS a 6-gallon line on the 9-gallon container? Maybe there aren't any lines at all.
