Heatwave hacks: The bottle shower

With temperatures expected to soar this weekend, we are giving away a bottle shower - a rose attachment that twists into place on all narrow neck plastic bottles. When the bottle is upturned, the device delivers a constant flow of water without any need for squeezing. A two-litre bottle holds enough water for a shower lasting almost two-and-a-half minutes and water left in a plastic bottle in the sun can become surprisingly hot.

As well as a camp shower, we think it would be great for rinsing hands and feet on the beach or washing dog paws after a muddy walk.

Why it's important to reduce, reuse and recycle

If you include power plant cooling water, it takes seven litres of water simply to manufacture a one-litre bottle. To that environmental cost you can add the 162g of oil required to make the plastic, all the associated CO2 emissions and the millions of tons of land fill or ocean waste to which the bottled water industry contributes.
