Which Beer Will Be Filled First?

Can you work out from the image below which glass will fill up first? There is only one tap and so many pipes. So where will the beer fill up first? We have written the answer below but give it your best shot before you peek! Let us know in the comments how you get on :)


So were you able to work it out?


The beer that filled up first was 6! 

Take a closer look at the pipes if you're not sure...some of them are actually closed!
