2P's bean experiment is proving to be a real source of interest. Our bean that was planted in soil and is receiving water, the right temperature and sunlight is growing very healthily. It is dark green and seems to have a strong stem. The bean that was placed in the cupboard however is very different. It is significantly taller but the stem is much weaker and the plant is a much lighter green. We were surprised that the bean planted in the sand has sprouted as it has not been watered. On closer inspection we noticed that there were some condensation droplets in the pot so we think this might have helped to make the bean sprout.
