Fail Innovation-Invention?

Have you try to make something new or develop from something? Have you ever know that not all innovation and invention that have been created but never reach our century. So i will show you some of the 'fail' innovation and invention.

Wow i know why all the things never reach our century. It just  causing 2x possibilities of having lung cancer

I think this is not the best way to bond with your family. Ii think i just can cause injuries or even death!!

What i think is that all the inventors just making this for fun or without thinking consequences of using the invention in daily life. To make a successful invention or innovation, I think we need to think deeply about possibility and try think creatively how to make it be use by all people.
