- Carefully pour the sebacoyl chloride solution on top of the hexamethylenediamine solution (both are available from chemical suppliers). If you have trouble keeping the chemicals in separate layers, ask a bartender for help.
- Use tweezers to grab the layer between the two liquids and pull it up.
- The thread will appear as fast as you pull it from the mixture. You can collect it around anything that´s convenient. I used a roll of paper towels stuck on a paint roller.
- The final product: thread-from bottles of chemicals.
