Mata-moscas do caraças! Um Case Study...

Tenho de confessar que esta é uma das tais ideias que eu gostava de ter tido...
Matar as Moscas e Melgas, etc... Só com Sal de Cozinha!
Notem que este Inventor  mexeu o Coiro, e lançou a ideia através do Indiegogo, depois de ir até à China(!) só para garantir que o Produto Final era mesmo o que ele queria, e como ele queria...
ASSIM É QUE É!

Pump action Bug-A-Salt takes down insects in a hail of table salt
By Darren Quick
We recently took a look at the InaTrap insect trap that lures insects into its designer-inspired form to quietly and efficiently send them to an early grave. But if you’re looking for something slightly more badass that provides a greater sense of satisfaction when taking out those pesky bugs then it’s hard to go past the Bug-A-Salt. The brainchild of Santa Monica-based artist Lorenzo Maggiore, the Bug-A-Salt is a pump action gun that takes out pests in a blast of non-toxic table salt.

The “insect eradication device” has an effective range of three to five feet (0.9 to 1.5 m) and holds enough salt for around 50 shots. Once filled via the loader cap on the top, the gun is primed by pumping the handgrip. This activates the pop-up sight for taking aim and the auto-safety, which needs to be manually disengaged before firing. This is because firing it into someone’s face is likely to sting quite a bit and could potentially damage an eye.
