Ok, so my group decided to watch a Ted Talk based on the Livesaver bottle. The Lifesaver bottle transfers dirty, brown, muddy water, into freshwater. What you do is, scoop up the dirty water, close the lid, pump the bottle a few times and just like that you have clean, potable water. This invention is a positive change in our world because if you live in a country with dirty water, you use the Lifesaver bottle and now you have got clean, fresh water. This is cool seeing what other people think of this and they respond. It’s cool how one idea can have an impact on the world.
