I found this concept device on Kickstarter and I thought it useful to share with you. The absolutely astonishing amount of plastic bottles that everyone uses and throws into the garbage can every day is truly impressive. This represents an economic waste, since the plastic of bottles is a commodity that is worth money and can be reused. Also, from an ecological perspective, this poses several problems.
Pavel & Ian developed “Plastic Bottle Cutter”, that is a smart pocket-size tool with which you can very easily cut any plastic bottle – of juice, soda or other – into a fine plastic rope that can be used for just about as many purposes as you can think of.

If you like projects that center on the upgrading of old objects, then you will surely like this next one. It is also a recycling project as you will need to find a new purpose for your old DVDs that you don’t need anymore. The tutorial will teach you how to make a Birdbath with a mosaic look by using recycled DVDs. Maybe you already have a birdbath at home, but if not you can buy one at a local store. In case it has some cracks, don’t worry as they’re of a special material, called J-B Water Weld, that will help you repair the cracks in the birdbath. When it comes to the DVDs, you should use only the silver colored parts as they will create a shiny effect.

Start cutting your DVDs into 6 or 7 equal pieces, but don’t separate these pieces from the center of the DVD. Rip each piece from the center by hand and repeat this process until you have enough tiny pieces that can cover your birdbath. In order to protect the silver shine of the DVDs you should use Krylon Crystal Clear Gloss and spray each little part. When the pieces have dried, start gluing them on the surface of the birdbath, creating any kind of pattern you want. You can use Liquid Nails Clear Seal to glue them. When the glue has dried, apply some grout between the pieces of mosaic and that is all. This will keep the little bathing birds protected as their feet won’t get stuck between the cracks of the DVD pieces. Go outside and find a nice place for this unique decoration in your garden.
