You want an idea and make something?
I have a friend that has a gadget that I manufactured for him but cost
megabucks here to get going.
It fits on the end of a vacuum cleaner and you can use it as a powerfull
blower while providing un unloading to stop the vacuum cleaner from
overheating.
Could be moulded in plastic and be everybodies cleaner of difficult places.
price made up $ 5.00 with a profit margin of 40%
Interested to give it a shot ?
