Materials:
Higlighters 8x
Toy Car 1x
Ramp 1x
Pencil led holder 1x
Balloon 1x
Eraser/Sharpener 1x
Pin 1x
Tape x1
Scissors 1x
Procedure:
1. Place the ramp so that one side is high and one side is touching the ground.
2. Make a sewsaw using one highlighter and the pencil led holder and place the whip on the higher side of the ramp right at the edge.
3. Place the other 7 dominoes in a Pattern where the last dominoe can hit the high part of the highlighter that is used for the whip.
4. Tape a pin on the toy car at the frontso that it can poke something.
5. Place the car at the top of the ramp behind the whip.
6. Blow a balloon to it's max sizes.
7. Make a knot at the opening of the balloon.
8. Tape the balloon at the floor or surface directly behind the lower side of the ramp.

IMPORTANT: Each time you let the car drive down the ramp and pop balloon, you need to repeat step 6-8.

9) Vinegar
10) Paper Towle
ADULT SUPERVISION

# data[].attributes.body
1) Cut 12 inches of strong tape.
2) Tape 3 pencils to the bottle with strong tape.
3) Use a funnel, and pour in vinegar until it fills up half of the bottle.
4) Separate the paper towel into a single layer.
5) Tear off a smaller piece of paper towel.
6) Measure out 1 tablespoon of baking soda,
7) Put the baking soda on the paper towel.
8) Wrap the baking soda in the paper towel.
9) Put the baking soda inside the bottle and quickly put in the rubber stopper. Give a few shakes, and stand back, or you'll smell like a vinegar and baking for rest of the day!

1) 2 cans
2) 2 book covers
3) rubber band
4) Popsicle

# data[].attributes.body
we took the cover and the back of a book and cut them  6 cm thick and stuck them together to make it stronger we also took 2 empty soda cans and stuck them under covers.
then we put a few Popsicles at the front side so we can put the rubber band around it so we can shoot something

Elastic Potential Energy

# data[].attributes.body
First stack four Popsicle sticks up and bind them on the ends with rubber bands. Second attach two Popsicle sticks at the end with rubber bands then pull the two sticks apart and put them on the other stack of sticks with one stick on the bottom and one on the top ( make sure the sticks are aligned and in the middle of the larger stack). Finally hot glue the bottle cap to the top stick.

Kinetic Energy

# data[].attributes.body
The energy that let the dominoes fall over was mechanical energy. The energy that held the car was gravitational potential energy. Gravitational potential energy of the car turned into mechanical energy letting the car move. The car hit the balloon with the pin first. Letting its strain potential energy turn into mechanical energy by letting it pop and sound energy hearing the bang.
