1. A dock needs four toothpicks. Glue two toothpicks together, and then connect two toothpicks together to form four. Cut a gap where the pier is to be glued with scissors, and then glue the pier and the bridge deck together to form a triangle. This is because triangles are stable. This completed four columnar "piers".

2. Choose an appropriate number of toothpicks according to the required length, arrange them neatly, and then cut off the tips of toothpicks with scissors, which is not only for beauty, but also to prevent toothpicks from scratching their hands. Then mark two positions on both sides of the bridge, put two toothpicks side by side and stick them at the previously marked positions as pillars on both sides of the bridge deck. Then, stick two pieces horizontally on the back as the bridge deck. In this way, the toothpick bridge will be more stable.

4. Then mark two positions on both sides of the bridge, stick two toothpicks side by side, and stick them at the previously marked positions as pillars on both sides of the bridge deck.

5. Finally, make other bridge decks in the same way, then add approach bridges on both sides of the bridge deck and fix them, and the toothpick bridge is completed.
