On Friday’s Margaret’s Science club have been having lots of fun. Last Friday we investigated if we could clean dirty pennies with household products. We used lemon juice, salt and vinegar, soy sauce, ketchup, hot sauce, washing up liquid and coca cola. It was amazing to see the results. I don’t want  to tell you now and spoil your fun if you want to try it at home. All you need to do is pour in one of the items into a cup and drop the  dirty coin in for fice minutes and then take out and dry. I think you may be surprised at the results!
