Bottle Rocket ~ Newton's Third Law of Motion

   Who doesn't like rockets? Besides the fact that they are pretty cool looking, you can watch them launch up into the air. We will show you how we made a rocket using Newton's third law of motion which states that when a force acts on an object, the object will push back in the opposite direction with equal force.

 

You Will Need:
•Empty plastic bottle
•Card-stock
•Tape
•A cork
•Air pump with needle adapter
•Water

 

   First use the card-stock and tape to decorate your rocket anyway you would like (we cut out four fins for the sides and a cone for the top). After you're done with that fill a quarter of your bottle with water. Take the cork and press your needle adapter to your pump all the way through it. Next place the cork inside the mouth of the bottle and attach the back of the needle adapter to your pump. Start pumping air into the bottle, making sure to aim it away from you and anyone else, after a few seconds you should have liftoff!

Making Marshmallow Shooters

 

My kids grandparents went to a Fall Festival last weekend and came back with two marshmallow shooter kits for the boys. The marshmallow shooters were very easy to put together and all the supplies can be bought at a small hardware store. For one shooter you will need a total of 31 inches of 1/2 inch PVC pipe, two 1/2 inch PVC elbows, two 1/2 inch PVC tees, two nickels (yes as in money), and one 1/2 inch PVC coupling. You will need to cut the 31 inch PVC pipe into six 4 inch long pieces and one 7 inch long piece. After that I have attached a diagram showing you how the pieces fit together. Nickels are used to block off passages to give the shooter more air power.The mini marshmallows fit into the shooters perfectly without getting stuck. Also do not glue the pieces together, you will need to be able to take the shooter apart to clean it. My boys had tons of fun with this project, and since it was chilly outside, I let them play with it inside (luckily we have tile floors, I would imagine the marshmallows would stick to carpet) and they did not want to stop.

Using plastic bottles & socks to make Bubble Foam

  

    What kid doesn't like playing with bubbles? My kids play with bubbles on an almost daily basis and enjoy every minute of it. In this project we will be using an empty plastic bottle, a sock, scissors, and of course bubble solution. First you need to use the scissors to cut the bottom off of the plastic bottle. Then simply place the sock over the hole you just created on the bottom of the bottle. After that just dip the bottom of the bottle into the bubble solution and blow on the mouth of the bottle to create foam. The kids will love it. You can use any size bottles or socks, I just found the smaller ones to be easier for my young boys. If you don't have any socks you want to use, an old t-shirt or blanket will work as well. You would just have to cut a piece out of the fabric big enough to fit around the bottle and cover the hole and secure it in place with a rubber band.
