Streszczenie
We prove that the product of any two non-degenerate plane continua contains a non-degenerate hereditarily non-weakly chainable continuum. Consequently, in the product of two pseudo-arcs, there exists a non-degenerate subcontinuum containing no pseudo-arc. This answers a question by D. P. Bellamy.
