Getting started
Motivated enough? Let's begin with building of our crane!
Material Requirements:
| Material | Quantity | Dimension/ size/weight (if applicable) | Alternative (if applicable) |
| Cardboard Tubes | 4 | 3” - 5” | Toilet paper rolls |
| Paper cup | 1 | Standard | - |
| Pencil | 3 | Standard | Wooden skewer |
| Cotton thread | 1 spool | - | - |
| Sample weights | magnets/marbles/keychains/keys | - | Anything lying around at home can be used |
| Paper Clips | 4 | 50mm - 80mm | - |
Step 1: Let's take two cardboard tubes and join them together using the duct tape.
Step 2: Take a cardboard tube and draw two U-shapes. The other U is right at the back of the first one.
Step 3: Cut these U shapes out. Repeat the same process for the other cardboard tube as well.

Step 4: Let's put the two pillars we made around a cup to see how does it look.
Adjust the pillars so that all the slots are properly aligned with each other and place a pencil at the top.
Step 5: Take the thread pool and cut out a piece of 12" in length.
Step 6: Now, attach one end of the string to the center of the pencil.
Step 7: Let's take two paper clips and turn them into the following shapes
- Create a hook, like an 'S' shape.
- Unbend the second one to form a straight wire.
Step 8: Attach the 'S' shape hook to the thread with a pencil. And pass the straight wire through the cup.
Step 9:
- Put the bucket between the two pillars.
- Put the pencil at the top.
- Connect the hook to the bucket.
THAT'S IT! NOW PUT IN SOME WEIGHT, ROLL THE PENCIL AT THE TOP AND SEE THE WEIGHT BEING LIFTED!
