# Puzzle To Find The First Full Bottle Of Water

#### The first full bottle of water is a puzzle to discover.

Many people have been left perplexed by the seemingly easy challenge.
Find the solution to the question of which jar in the image below is full of water first using your physics knowledge and a little logic.

Which tank will be the first to be filled? Will tank 1, 2, 3, or 4 be the first to fill? To work this out, you’ll need some physics knowledge.

If you don’t know what to do or can’t locate the answer, check out the solution below!

#### This is the answer – but there’s a catch!

Tanks 3 and 4 will fill at about the same time, according to the response! Because water will flow from the pipe in tank 1 to tank 2, tank 1 cannot be filled first because all of the water will flow to tank 2. Tank 2 cannot be filled since adding water to it will cause it to overflow into tank 3. Tank 3 might have been filled first, but it includes a conduit at the top that would have allowed water to flow to tank 4. When tank 3 is filled with water, it will almost fill to the top, but once it hits the pipe, the water will be transferred to tank 4.

When tank 4’s water level reaches the same level as tank 3, the water from tank 2 will be evenly split between tanks 3 and 4, and the two last tanks will fill at the same time. Then tank 2 will be filled, and finally tank 1 will be full.

You, my buddy, are a genius if you got the proper answer!
