stuck on 55 I W and 37 0n N C

Help please! stuck on 55 inventors workshop and 37 on new challenges

Hi, this one really is trial and error, my solution differed quite a bit from the games "Plan". The main thing is placing the first domino so that the ball hits it and it falls onto the next domino which should fall down onto a carefully placed domino on the board below which in turn knocks down the next one to the right. This 4th domino should then fall down to where it will knock one domino to the left and one to the right. The one to the right should knock down the last domino on that side into the right collection area. The domino on the left should fall down and hit a domino on the lowest board and in turn knock down your last domino into the left collection area. You will have to use trial and error. Start from the top and work down testing each domino plaement one at atime. Good Luck with this one

Sorry I've only got as far as level 11 on NC myself

solution for 37 on NC:
Place the candle near the torch and the boiler above the candle. connect the boiler to the steam whistle using the pipes given. (Make sure that steam comes out of the boiler wants u start the experiment).
Place the bellows beneath the billiard ball so that the bellows start up the windmill and the ball falls on the torch to light it up.
Place 2 gears to the left of the gear which is already on the screen, so that you will have 3 gears connected horizontally.
Using the rubber bands, connect the first left most gear to the windmill and the middle gear to the upper conveyer belt.
Place the electric motor under the power disrupter and connect them with a cable.
Place the 3 remaining gears vertically beneath the electric motor.
Using the remaining rubber bands, connect the up-most gear with the left conveyer belt, the middle gear with the electic motor and the bottom gear with the right conveyer belt.
