All we need is for Alex to invent a four dimensional hose. It's impossible to tangle a four dimensional hose in three dimensions, as you'd just be able to pull it through any obstacle without it actually passing through it in any meaningful sense.
All you need is a hose that is movable in time as well as space. So, effectively, you'd just pull the hose through the space currently occupied by the wheelie bin wheel at a time when it wasn't there. In our pitiful three-dimensional perspective it would appear to pass through the wheel. A suitably temporally flexible hose would do the job.
Come on Alex, how hard can it be?
