Make a Bouncing Polymer Ball - Experiment with Polymers

Make a Bouncing Polymer Ball - Experiment with Polymers
Introduction Balls have been toys practically forever, but the bouncing ball is a more recent innovation. Bouncing balls were originally made of natural rubber, though now bouncing balls can be made of plastics and other polymers or even treated leather. You can use chemistry to make your own bouncing ball. Once you understand the basic technique, you can alter the recipe for the ball to see how the chemical composition affects the bounciness of the ball, as well as other characteristics. The bouncing ball in this activity is made from a polymer.

Song Lyric Wall Art / D.I.Y. Project A couple weeks ago, I found a paint-by-number at an unbeatable price. I can't pass these things up even though I already owned this particular design. I thought that I could maybe use it to make a fun D.I.Y., but my new rule is that all thrifts that I purchase with the intent of restyling need to get done right away. I have way too many half finished projects in my life. vintage belt frame I’m sure you’ve seen plenty of wayward western belts at vintage shops and thrift stores.

Organic Gardening… Growing Seedlings in Recycled Containers (tutorial) I have been saving some old boxes and cardboard tubes and plastic lids and such for the past several weeks… it’s so wonderful how you can recycle things you find around your home into something you needed and wanted, for free! Today I’ll show you two different ways to create mini-greenhouses for your precious seedlings. Here are just some items from a large collection of recyclable goods I’ve been saving. After the planting season, I’ll just rinse out any plastics I’ve used and toss them back in the recycling bin. The cardboard I generally just plant right into the soil with the seedlings… that’s the advantage of using toilet paper and paper towel cardboard tubes for your seedling pots.
