refined sugar

5 spoonfuls

condiments

sodium bicarbonate

1/3 spoons

step

1. Put white sugar or yellow sugar in the spoon.

2. put it on the fire and stir it with chopsticks while burning.

3. Add a little baking soda after the sugar is completely melted.

4. When the color changes after a few seconds, take it out and pour it on the tarpaulin (if it doesn't work, put it on something that doesn't stick).

Because there was no special tool, I folded the tarpaulin and flattened it with something. There should be a special molding tool.

It takes about 6.30 seconds to harden, and it's ok ... The last piece is not taken well and broken.
