Meet the Biem Butter Sprayer: a handy tool that lets you go from a butter stick to butter spray in seconds. It sprays real butter and works with your favorite brands. The device does not melt the whole stick or overheat your butter. It has an accelerometer to know when you are picking it up.
Biem does not require you to use any chemicals to get started. It melts only the amount of butter you need. Yet another interesting Kickstarter project.
