What a brilliant invention idea! so unique and well thought about. The Fishes will certainly swim away from plastic once they have been sprayed with Plastic Repellent. The instructions are so simple to follow and your chosen ingredients are super! The pencil poking feeling which the fish get from the nettle chemical will keep them away for sure. making it clear that it is not for use in rock pools is a good idea, these fishes could be helped by people picking out any rubbish instead. Excellent work Ava, well done.
