Inspired by pictures I have seen of water crystals taken from different places I decided we would give this experiment a try.
I encouraged everyone in the house to partake but I think there was only Hermione and myself who conversed with the rice. Nana certainly didn't and thinks I am now officially crackers!
Here are our results. The 'good' rice looked as it did when we put it in the jar and although it smelled a biy musty it didn't smell particularly bad. The 'bad' rice in comparison had green mould on it and absolutely stunk.
Nana feels the whole thing was not scientific as the jars and amounts of rice varied slightly. I agree it wasn't scientific in the true sense but that's not to say it isn't interesting.
Hermione and I talked about it in the context of how we talk to other people (as well as things like rice) and I hope this has helped her to see how damaging or nurturing our words can be.
