Can someone tell me a good way to collect hydrogen?

A few days ago i started separating Hydrogen and Oxygen from water (with electricity of course) and saw that Hydrogen was very combustible.Can anyone tell me a good way to catch it (i tried a few ways but it either blows up or doesn't have enough pressure to go out of the tube and sometimes both) or just a way to collect it and have pressure?

Don't try using a fishing-net.
What exactly have you got there generating gas?

I made sort of a coil and another coil around it because the more there is the more it lets out but it's hard to explain so i will post a pic of the thing and a pic of it making some Hydrogen (the pics are from a test...It's in a ashtray btw the hydrogen in the picture took about 0:30-1:10 min to make or less)

That looks like you've got plenty of surface-area, how about a swan-off PET bottle?

It worked but i hot a better idea i made a new thing that separates aster and gives out more and it came to me: just put the thing in a small 500ml bottle make holes for the cables sale those holes and just make a hole in the top for the hydrogen to escape or something else, i will post a pic o it as soon as i make it work

Yes, I'd like to see it.

As a passing comment Hydrogen will not explode spontaneously,

This is pure Hydrogen w/o Oxygen (i think), it blows up and doesn't burn (it will burn if i get the hydrogen and oxygen to mix properly), the last time i collected it in a tube when i tried to lite it it blew up harder than a firecracker...(My English sux because i am from Bulgaria....So if i wrote something wrong i am sorry...)
Bulgaria Rocks!!!!

The accepted lab way to collect is t put a water filled tube/container over the appropriate electrode and allow the gas to displace the water leaving a container full of whatever at 1 atmosphere of pressure. if you need to fill, say a balloon then arrange a pump to transfer the gas to a balloon at pressure.
