The Horse and the Balloon, Walking on Water

People have imagined walking on water using wooden shoes, hot air balloons and a penny farthing. I hope that if we ever get walk on water technology, we go back to horse and carriage because for some reason it won't work with cars. Wheels roll the horses feet too. Can swim? Gay, i think so. Anyway, i'n see why the horse couldn't just swim. Whnever i've ever seen, i've neveractally seen a horse swim.
