My son is a passionate collector and loves empty plastic bottles. They play very well with us, especially when bathing, filling them up, and, of course, with a big spit, they spit in the bathroom.After a while, however, we will have so many bottles that we have to start with something, because it will not allow them to be thrown away. But after elementary school technology, I would never have thought I'd make something from reusable materials. Have you remembered your rinse-out hair bottle? I just remember that I couldn't manage to get my hair cut out because it was so hard and my hands were well wrinkled. Well, today's plastics are probably a little harder, and there are dads here, too, if they are not going to work out.
