  We present a new solvable system, solving the equations of five-dimensional
ungauged N=1 supergravity coupled to vector multiplets, that allows for
non-extremal solutions and reduces to a known system when restricted to the
floating brane Ansatz. A two-centre globally hyperbolic smooth geometry is
obtained as a solution to this system, describing a bubble linking a
Gibbons--Hawking centre to a charged bolt. However this solution turns out to
violate the BPS bound, and we show that its generalisation to an arbitrary
number of Gibbons--Hawking centres never admits a spin structure.
