Ever Blow Bubbles...?

This challenge is in the beginning of the level. Once you go through the doors make a right, there will be a broken bridge, you need to find the right bubble and walk/run in to the bubble in the direction of the bridge and it will shoot you in to the air and hopefully you will land on the platform.

I am not 100 % sure but either way the middle bridge is the easiest one to shoot for.
