Simple technological inventions that primary school students can make.

The manufacturing method of the glass candlestick invented by primary school students through science and technology is as follows:

Preparation materials: bottles, paper, scissors, glue sticks and pens.

1. When all the materials are ready, tear off the wrapping paper of the bottle, clean the bottle and dry it for later use.

2. Then cut the paper as high as the middle part of the bottle. It should be long enough to wrap the bottle.

3. Fold the length of the paper in half and draw a half heart shape.

4. Cut your heart. Cut it round.

5. Then spread it out, and a hollow heart appears.

6. Stick the cut paper on the bottle.

7. Next, light the candlestick and put it in slowly. A heart-shaped glass candlestick is made.
