I have not tried this yet, to see if it works. 😀

How to attach two wheelie bins, so that you can wheel them together with ease:

1. You turn both bins to face the same direction – with the green bin at the ‘front’ and the brown bin at the ‘back’.

2.  Open both bin lids

3  Flip the brown bin lid all the way back so that it is now inside the green bin, and close the green bin lid on it.

4. This creates a chain’ meaning the green bin can now pull the brown bin, making it one smooth motion to wheel both bins to the side of the road.
