Hello my dear friends! Roman is here with you as usual! Today I’d like to tell you how to make a speaker out of a simple balloon.

We need to take a scotch tape, a balloon, a magnet and a copper wire. So, let’s start!

First, we need to inflate the balloon. Then we take a magnet, put it in your hand and measure its size, we see that it’s approximately of the size of four fingers.

So we are going to wrap the wire around four fingers. We take a piece of scotch tape and fix the wires tightly, so they won’t unwrap.

We stick the bunch we got to the balloon with the scotch.

We have to get such a semi-product and the speaker is almost ready. We only need to connect it to the audio system, MP3 player, computer or another device you have got. We take these two wires and connect them. Done! Let’s test it! Turn on the music, bring the magnet.

That’s all! We have got such a speaker out of the balloon. Now let me tell a bit about quality and volume of the sound in this speaker. The first thing influencing the volume is the balloon size: the bigger the balloon – the louder would be the sound. The second thing which is important for the volume of the speaker is a wire. It’s better to chose a thiner wire, because the volume depends on the coils number. The more coils you have – the louder would be the sound of the speaker. The third thing is a magnet. It’s better to take a neodymium magnet, as it has better gravity than simple magnets do. That’s all for today. Thanks for your attention!

By the way, I’d like to thank you for your suggestion, for your activeness in comments. I’ll try to make a video about an electric shocker and a metal detector, as I haven’t got all the materials at the moment. That’s all! Thank you all for your attention! Bye everyone!
