Abstract: We give an example of a weakly infinite-dimensional space $ X$ such that the product $ X \times B$ of $ X$ and a subspace $ B$ of the irrationals is strongly infinite-dimensional; under the assumption of the Continuum Hypothesis, $ B$ can be the irrationals. This example answers a question of Addis and Gresham [AG].
