DIY 2-Ply TP
The children at this school were disappointed that the school’s administrators wouldn’t spring for two-ply toilet paper. If everyone washed their bottoms with a bidet, nobody would be in this mess, yet here we are. Anyway, the schoolkids took it upon themselves to engineer their way out of the cheapness of their school.

They inserted two single-ply rolls of toilet paper in a single toilet paper holder. That way, they would have twice as much toilet paper to wipe after they were done dropping a bomb. In the end, the school would end up paying twice as much for TP.
