An iPhone Case For Sending Smoke Signals

This iPhone case lets you send smoke signals, now why you would want to do that, I have no idea. But It’s certainly a unique idea.. It’s called the SMS case which stands for “smoke messaging service.” It’s a case designed by Dennis de Bel which hides a chamber filled with lamp oil inside.
When you press the button on the case it heats the lamp oil up to produce clouds of smoke. Of course, in order to respond via smoke as well, others will also have to have an SMS case. But to be honest, I have a hard time believing anyone would actually use a device like this.
