Innovative, Scientific and Practical Handmade Works in Grade Four

Materials needed include an idle glass jar or jar and a small piece of tin foil?

Production steps:

1. Cut the tin foil to a size just enough to fit in a glass jar, and draw a bitmap of each constellation with strokes on the back of the tin foil.

2. Then poke a small hole in the tin foil according to the constellation lattice with an awl or a sharp needle?

3. Roll up the tin foil and glue the two ends with transparent glue to make a tin foil cylinder engraved with constellations?

4. Carefully put the tin foil cylinder into a glass jar or jar, and then put it into a small LED wall lamp with button cell. If there is no led wall lamp, you can try to open a hole from the bottom of the jar, then light a small candle on the glass bottle cover, and cover the glass jar with tin foil upside down to make a starry candle lamp.

5. Turn on the power supply, cover the bottle, and use the hand-made starry lights to complete a waste.

Materials required: Scrap iron cans (cans, milk powder cans, paint buckets, etc.). ), nails, hammers, and computers with printers.

Making a tutorial:

1. Download the following drawings through a computer with a printer, and enlarge and print the drawings according to the side circumference of the actually used scrap metal cans.

2. Wrap the printed drawings on the side of the scrap metal can and stick them with glue.

3. Punch holes with nails according to the black spots marked on the drawings, and poke holes with regular patterns on the surface of the scrap metal can.

4. After the hole is punched, tear off the drawing on the tin can. Lighting candles in it at night is a special kind of starry light.

In addition, waste paper boxes can also be made into starry lights, and so on.
