Watermelon consists mostly of water which makes up more than 90% of the watermelon. This is shown in this video as the water splashes out when the roller crushes it to bits. This was 6+ kilogram watermelon but the roller reduced it to pieces.The flesh of the watermelon is so soft. At first the roller had difficult to have a grip on the roller as there was less friction.
