I'll ask for help myself here, if you don't mind me hijacking the thread
In return, I'll help you solve Puzzle 42: Cannonball Hoop:
1. Grab the shelf and put it below the vertical one, to the right of the screen. You should place it so it forms an angle with the vertical shelf, just like a "V", but more open -- it will be used to make the cannonball go upwards instead of just colliding with the vertical shelf.
2. Place the Time Switch and the Gravity Machine near the socket, and plug them all. That is, one of the two power cables should go from the Gravity Machine to the Time Switch, while the other goes from the Time Switch to the wall socket.
3. Set the Time Switch to its maximum. You can do this by using the rotation arrows. Instead of rotating, the timer will be set up or down, depending on which arrow you are pressing, of course.
4. That's it. The rocket should bump the scissors, which in turn will cut the rope, and the candle should fall, lighting the fuse of the cannon just in time for the Time Switch to activate the Gravity Machine. Once the gravity has been taken care of, the cannonball will fly directly into the shelves, taking a 90º angle, going through the hoop. Just wait for it to fall down through the hoop once, and you'll be done with this puzzle.
So, into my question:
In Puzzle 44: Tarzan, what am I supposed to do? I know that I must activate the Magic Wheel, make it go up, then fall down on the bellow to propel the balloon rightwards, but I don't get how I should do this.
