A short essay of golden ideas created by primary school students
When playing table tennis, table tennis often rolls everywhere, and bending down to pick it up is time-consuming and laborious. Today we will make a simple and practical table tennis ball-picking tool.

First of all, you need to prepare materials: a mineral water bottle, a plastic hollow tube and glue.

Then cut off the bottom of the mineral water bottle, cut the bottle wall into a 3 cm strip at the bottom (table tennis can be folded inward without falling out), and then cut a hole under the bottle mouth of the mineral water bottle so that the table tennis can roll out. This hole is used to facilitate us to hold the ball.

Then we insert the plastic hollow tube into the bottle mouth of the mineral water bottle and fix it with glue.

Well, our production is finished, and a simple and practical table tennis ball picker is born.
