2. The showtime thing I had to c lighte was the first shelf where the ablaze(p) ball historys down. Then I had to hang up the 5lbs. then switch the sides of the chocolate-brown lever at the bottom. After I had to put the elastic of the slingshot with the little(a) ball. The last thing was hang the lay up. Part 2 The first to do is push the first domino. It causes the rest of the dominoes to wane and push the first strike hard ball. The criticise ball bequeath roll down the ramp. As the ball is rolling, it allow hit and push another pink ball.The second pink ball will roll down into a thin skinny tube. When it falls, it will push up the other side of the lever. When it goes up, it will absolved the string loose and make the cut cut the string. When it cuts the string, the weight will fall and break. When it breaks the body of body of water inside of it will go through the tube, pouring inside the lay. The bucket will get heavy and split down the string, which the en d is tied to the hat of a cookie jar disruption the cookie jar. Analysis questionsIn the device, it shows a closed system because all of the items outride in the area. The items were the 2 balls, the bucket with water and the dominoes. 2. To change a thermos into an open energy system is by fountain the eyelid. 3. Energy is never created or unmake it is just passed on to other divergent types of energies, like potential to kinetic or potential to mechanical energy. 4. One note is where the dominoes fall and push the first ball. The second is when the bucket full of water pulls down the string to open the lid of the cookie jar.
