do you know that post-it notes were invented by accident when someone made a glue that did'nt stick properly.You could stick down a piece of paper,peel it off and then re-stick it.
Some inventions are just for fun.Some of them were made to make our life easier.In conclusion,we're all need to think even further.Maybe someday,we will invent something that everyone will use.
