It’s confusing whether these inventions are really priceless or some silly things which are just a waste of time. Don’t you also feel the same? It is because they all seem completely weird and useless.
Just because they look weird doesn’t mean they’re inefficient, only putting them into test can say whether they’re stupid or not. However, according to me although these cool inventions seem weird, they’re indeed a work of pure genius and I really need some of these weird but genius stuff in my life right now.
