Are you tired of spending a lot of money on dedicated fabric softener sheets to ensure that your laundry doesn't come out too stiff and dry? It turns out that a simple tennis ball is a great substitute for this product - all you have to do is wrap a few tennis balls in aluminum foil, put them in the washing machine with the clothes, and you'll be able to reduce static electricity and make your clothes softer. If you wish, you can add a few drops of essential oil on the balls to add a refreshing fragrance to your clothes.
Have you ever had your bicycle fall to the ground because the leg that was supposed to protect it didn't do its job?
