i have to make a rube goldberg

i don't have any materials except for few dvds, toy cars, balls, and the professor doesn't want us to waste any money going to the store it has to be materials in the house

and i need to wateer a plant, turn the page of a book, pop a ballon, etc (either one)

what can i do

To create a Rube Goldberg machine using the materials you have at home, you can get creative and think of ways to utilize the DVDs, toy cars, balls, and other household items. Here's a simple idea to get you started:

Objective: Water a plant

Materials needed:
1. DVD case (as a platform)
2. Toy car
3. Small ball
4. String or thread
5. Plastic cup or container (filled with water)
6. Scissors
7. Cardboard or cardboard tube
8. Rubber band
9. Stick or ruler (to act as a lever)
10. Tape

Here's a step-by-step guide on how you can construct your Rube Goldberg machine:

1. Set up the DVD case vertically, with the open side facing down. This will act as a platform to hold the other components.

2. Attach the cardboard or cardboard tube at an angle to the DVD case, creating a slope. Secure it using tape.

3. Place the plastic cup or container filled with water near the end of the cardboard slope.

4. Attach a piece of string or thread to the toy car. Make sure the string is long enough to reach the other end of the slope.

5. Attach the other end of the string to the small ball.

6. Create a small hole in the bottom of the plastic cup, just large enough for the string to pass through.

7. Place the small ball on the slope close to the top, and position the toy car on the bottom part of the slope.

8. Place the stick or ruler horizontally, with one end resting on the DVD case/platform.

9. Attach a rubber band to the loose end of the stick or ruler, and hook the other end onto the small ball.

10. Position a book on the DVD case so that when the ball hits the book, it will turn the page.

Now, let's see how the Rube Goldberg machine works:

1. Pull the toy car back to create tension on the string.

2. Release the toy car, allowing it to race down the slope.

3. As the toy car moves down, it pulls the small ball attached to the string.

4. The small ball rolls down the slope and pulls the string, which is threaded through the hole in the plastic cup.

5. As the string is pulled, it tips the plastic cup, pouring water onto the plant.

Remember, this is just a starting point, and you can add more components or modify the machine to achieve additional actions, such as popping a balloon. Be sure to use your creativity and experiment with different arrangements using the materials you have available.
