The experimental materials are as follows:
1. White sugar, 400g.
2. A new brush.
3. Paper cups, two (one for sugar water and one for water).
4. White paper, 2~3 sheets.
5. Lighter.
The experimental steps are as follows:
1. Make a cup of concentrated sugar water, it must be strong, and there is not enough sugar.
Take a piece of white paper and lay it flat on the table. Write or draw on it with a brush dipped in sugar water.
3. When the sugar is dry, bake it with lighter. Newly written words or pictures will appear.
The experiment is finished.
