Hints:

* You can use thumbtacks at first to support the bricks and then replace them with bubbles.

* For an extra challenge: can you release falling bricks and rising bubbles so that they will meet at the right point and catch each other? (You need to set up the neighboring columns of bricks first so that the bubbles cannot escape.)
