A week ago I mentioned our new régime for watering the garden. This is working really quite well, but as I said at the time, driving a car with two 80litre bins full of water does require smooth driving. This isn't an issue for me, but with the best will in the world driving up a rutted dirt track is never going to be as smooth as the situation requires. The main problem is that the lids don't seal: these are, after all, garbage bins.
This led me to some wonder if there was something I could do so that I can take the bins more than 1/3 full without filling the car with water.
The answer is "yes".
The problem is that water slops around - as you go over a bump is creates a wave, which pushes the lid up, and water gets spilled. What is needed is a baffle, so that the waves don't develop peaks. The solution is plastic bags - just lay a thick plastic bag on top of the water, with the ends of the bag going up the side of the bin and caught under the lid.
