Today’s invention is a stunt vehicle which works on the same basis as the Barnes-Wallis bouncing bomb (actually more like the Waboba).
A low-weight car with extra-large, deformable tyres would accelerate to up a shallow ramp and fly across a water surface at high speed.
Just before hitting the water, its front wheels would be spun about vertical axes (red) so that their rotation was now in the backspin direction.
This would allow the vehicle to skim (for at least one bounce) across the water and land on the opposite side of eg a river.
This could be used as a magic trick or as part of an advertising campaign.
