Making a rubber bulb shutter release?

So Id like to make a rubber bulb shutter release. Im looking on Amazon and other sites and see that rubber bulbs themselves are for sale. ($4 to $8) and I would think a gasline hose from the locsl hardware store would serve as a tube. ($2-$4)

My question would be this.. does the size of the bulb matter as per force applied? Larger bulbs would force more air, but do smaller work just as well foe the application?

Based on prices.. bite the bullet and buy a premade one? ($25 -$27) but they seem to have longgg tubes etc.
