Solar Balloons Experiment

Hi friends, welcome to Tech! In my hand, I've solar balloons. I'm gonna do an experiment with these balloons. Most people wouldn't have seen this. We can enter into the video but before that, I'll introduce a website to trade and make money. It's Binany. Trading means making money with money. Those who dont have an idea about trading, please don't lose money. Learn about it well and you can play along and make money. In this website once you make money, you can withdraw via PayTM. Binany website URL is provided in the description box below. Without delay we can go to the experiment. Let's go to the workshop. Friends, I'm gonna open the balloons now. 

This is 50ft long balloon. When we open the pack and take it out, this is our balloon and looks lengthy. There's thread inside it. Let's see how long this is. We'll lay it here and keep going.   It's too long. When we lay it downa and stretch it, we can see the length. So sun is out. Only when it's sunny, we can get good results.   So we've reached the end of the balloon. This is the end and when we open it... see it has this much width. It is wide as well. So we're going to tie up an end. So this end, we can just tie it up to avoid air leakage. We've tied on one side. Don't bother about this side now, the work is on next side. So, next we're going to fill air inside this. We can blow like a normal balloon as it is huge. 

So we're gonna use the natural air to blow it up. If there is wind on a particular side, we can just hold it like this. We'll try running. We need to run fast... Nothing happened. Air has filled a bit but not completely. So we have filled it. Had to run several times to become like this. It has started to rise and we can tie this end. We're tying this end now. See the balloon, it looks like an arch. Don't hold it! We've not tied it yet. So we're tying the end with the thread we got with this. If there are cloud covers, when we leave it, there are chances that it wont rise. Friends, see our balloon it has started to rise well.   It comes down whenever there's cloud. According to the sun, the balloon gets its power. If we hold it for a while, balloon might come at 90 degrees. It's coming along now. 

We'll just leave little bit holding the thread. Since there is breeze, it is tilting towards one end and going. See our balloon. It's awesome! Do you remember, we made a hot air balloon. It has a similar working principle like this. If it rises then we can't catch it. I've not tied thread now.   Try leaving it. So don't you wanna know the working principle behind this solar balloon? This balloon is made up of a thin material, like a plastic sheet. The company has gave that sheet color as black. The specialty of black color is since it is a dark color, it will attract the heat. The air inside the balloon gets hot and once the air gets hot, the density goes low. Since the density is low, there is the tendency of air moving up. That is why this balloon rises up when it is sunny. Solar balloons are mainly used for Earth innovations, projects in mars. What else... we can use it as a fun toy. 

We don't need to fill it up with Hydrogen or Nitrogen or Helium. Even without that, see. It's rising upwards like an arch. So we're gonna tie on both sides.   With this, we're gonna make like a raft. Anyway we saw the balloon rising up, now we can try this. It might end up tearing off. Let's place it in water. Lies like a raft in water. Next, I'm gonna sit on this. Not sure what'll happen.
