Use Water Wisely! Water is an incredibly important resource and we should all try to think responsibly when we use it. If you don't want to make any extra swirls then print our Bathroom Face Wash and/or Kitchen Sink Swirl-Direction Recording Sheet and note your and your family's observations for a week.
What to do: 1 Drill a small hole in the bottom of the tub- not more than 1cm in diameter. 2 Plug the hole with the stopper from underneath. 3 Place the tub in a secure position on the support structure. Position it in such a way that it won't fall off and you can easily remove the stopper. 4 Place the large bowl beneath the stopper, ready to catch the water when it drains out. 5 Allow the water to settle, preferably overnight or longer. To use a sink (or basin, or bath): 1 Put the plug in the plughole of your sink, basin or bathtub. Make sure the plug is one with a chain or a piece of string attached so it's easy to pull out! 2 Fill the sink up with water. 3 Float a cocktail stick or match on the surface 4 Allow the water to rest for as long as possible- a minimum of half an hour, but preferably overnight or even for longer.
