Query: 5-dimensional Bourgeois contact structures are tight   Given a contact structure on a manifold $V$ together with a supporting open
book decomposition, Bourgeois gave an explicit construction for a contact
structure on $V \times \mathbb{T}^2$. We prove that all such structures are
universally tight in dimension $5$, independent on whether the original contact
manifold is tight or overtwisted.
