The Slosh Tube is a bit of PVC pipe about 3 meters long, 4 inches thick, and filled with 20 litres of water. You can build one for approximately $20.
It’s surprisingly difficult to control the Slosh Tube, because the water in the tube is always moving around – just when you think you have it stabilised, the water moves again, throwing you all over the place.
I could really feel my entire mid-section getting a good thrashing – the balance required to hold this thing is incredible. I would recommend this to anyone who wants to improve their core strength and balance. Check out the photos (below) to see me and Owen getting completely owned by this evil device.
