HMS Flake 99, the world’s first amphibious ice cream truck, took its maiden voyage on the Thames in London this week. Captained by comedian David Mounfield, who won a contest for the post, the sea-going ice cream truck was commissioned by Cadbury in honor of National Ice Cream Week. The HMS Flake 99, which has a top speed of 5 knots, will be turning up on waterways and beaches throughout Britain this summer and it may even sail across the Channel to visit the Continent.
