It has been living under the boot of the car inside the spare tyre since godknows how long. An at the time random purchase along with spare guys and some pegs.
OMG what a godsend it was this week.
The site we stayed at was utterly perfect in every way apart from the sodding showers, which despite being immaculate and huge only produced a child's wee trickle of alternating freezing or scalding water for 20p which then cut out leaving you covered in soap with two moaning and equally soapy children after only a minute
grr
So out came the solar shower (basically large thick plasic bag with black on one side) plus tube, tiny water sprinkly end and tap wotsit.
Filled it up in the morning and left it black side up outside.
came back from beach and behind the tent showered and washed hair of both the dds (stood in trug) then I went into the utility tent and washed my hair and had a very decent strip wash with the rest of the warm water.
and all for FREEEEEEEEEEEEEEEEEEEEEEEEEE.
Granted it wouldn't work so well if it was cloudy but still...
was v pleased with it.
