Ok i dont know if any of you ppl are in orchestra but rosin that doesnt break so easily. Also bow hair that doesnt get dirty so easy. A type of shoe that has build in pad thing so it comforts the part of your foot that you seem to put pressure on. And an alarm clock that shuts up when you want it to like its voice operated. A type of asphalt that is more resistant to cracks and all that stuff. And a candy wrapper that doesnt make noise so you can eat it in class lol j/k. oh and snake you can always make a better type of rubber. So
And one last thing they are already trying to find another sorce of fuel for cars so far they try and use sunflower oil, water which heats up to form steam and solar energy.
