I really like your idea Yumna! It can be tiresome having to wait for mum and dad to sort out the bath, and getting the temperature right is really important, as no one like a bath that is too hot or too cold, brrrr! I like that it can also help you to wash your hair.... I think parents would still like to know when you're in the bath to make sure it's safe, what do you think you could add to your invention for that? Really good inventing, keep going!!
