Hello, this is my first instructable and I`m going to show you how to make a water mixer from plastic bottles. :)
First of all we need a:
a pair of scissors.
Take a plastic bottle and make 2 holes to fit your bot water taps and 1 hole at the bottom of the bottle.
Sorry, for pictue quality so you cant see the holes in it but there as I said to holes with same spaces that taps got and one in the other side in the middle.
Put it on tap`s and now you can easily fix the right warmness of the water. :)
Sorry for bad english ;)
P.S. This would be helpfull mostly in UK countries because there is double tap`s in the bathrooms. :)
