Immersion brewing without the right equipment

It’s been almost six months since I decided to stop buying more coffee equipment, and so far, I’ve been successful in resisting temptation. But I’ve been curious about how different my morning coffee would taste if I used immersion brewing, instead of my usual V60 percolation. To figure it out properly, I would have to buy either a Clever Dripper, AeroPress or French press. Or… I could hack something up, using stuff I already had in the kitchen.
