Look at this Milkshake Machine, it really gives you a perfect milkshake. It’s actually a large woofer connected with powerful amplifier. Watch the video…


“Take a powerful DC amplifier, connect it to a large woofer, feed the system with a signal generator, and at the end, just add milkshake. Of course it is also possible to measure the g-force of the shaking”
