Grow a banana plant (Musa ensete) in odourless rhino poo.
In the wild, rhino eat and then scatter a wide range of seeds in their dung, providing an ideal nutrient-rich place for young plants to grow. This dung is taken from UK zoos and safari parks and is treated to make it germ and odour free.
Simply sow the seeds, water the box and watch the banana plants grown. When bigger, plant out in a larger pot.
A white rhino weighs almost the same as 50 average-sized men.
