[Fluff]

This is a totally new method to me ,my preferred one is to stand in a bucket of luke warm water whilst wearing flippers ,this can be quite cramped depending on the size of the bucket  . Rather than use a battery I use  small solar panels and wait for a sunny day  , tedious but not as dangerous a a 12 volt battery in a jacuzzi  .When it stops raining I will give a report on my findings
