Materials Needed
- Glass bottle (clean and dry)
- String or yarn
- Acetone or nail polish remover
- Matches or a lighter
- Bucket of cold water
- Sandpaper (optional)
- Gloves and safety glasses (for safety)
Step-by-Step Instructions
Step 1: Prepare Your Bottle
First, make sure your glass bottle is clean and dry. This helps the string stick better.
Step 2: Wrap The String
Next, take your string or yarn. Wrap it around the bottle where you want to cut. Make sure to wrap it tightly. Tie the string securely and cut off any extra.
Step 3: Soak The String
Pour some acetone or nail polish remover into a small dish. Dip the wrapped string into the acetone. Soak it completely.
Step 4: Light The String
Put on your gloves and safety glasses. Carefully light the string with a match or lighter. Rotate the bottle slowly to ensure even burning. The flame should go out after a few seconds.
Step 5: Dip In Cold Water
Quickly dip the bottle into a bucket of cold water. You should hear a cracking sound. The bottle will separate at the string line.
Step 6: Smooth The Edges
Optional: Use sandpaper to smooth the edges of the bottle. This makes it safe to touch and use.
