The features and Advantages of PVC profiles
1–Water proof: Our Products are water proof and do not expand, contract or warp when they come in touch with water.
2–Fire Retardant: Our profile not burn itself: the product extinguishes immediately when the external flame source is removed. It has got an “A” class fire rating.
3–Excellent weather ability: Weather has no effect on PVC building materials. Problems like rotting, rust, etc. just don’t apply. Even in special conditions. Coast areas(Salt,Storm,Sun),PVC is more applicable.
4–Anti UV:Our profile has a good UV protection function, can give you a comfortable and healthy life.
5–Thermal Insulation: Our profile is designed with chamber style, has a good heat insulation performance. Its heat transfer coefficient is low, so I can keep your house warm in winter and cool in summer.
6–Durability: Our profile are very durable and last more than 40 years without color changes, damaged, etc.
7–Green environment Protection: Our profile use green formula and raw material (no lead), it is harmless to your healthy and environment.

This is a simple and effective way to make an Archery Target for Broadhead’s or field tips. This method usually takes around 30 minutes start to finish. You’ll need to buy a 4×8 sheet of polystyrene home insulation, at least one inch thick, and a can of adhesive spray like 3M Super 77.
You may not have a newton’s cradle to demonstrate newton’s 3rd law and the conservation of momentum; you can also use a line of coins. Dr. Smith has a line of five nickels. when he slides one nickel and strikes the line the nickel on the end shoots out. Two nickels, two shoot out. …..(make video, no slo mo)
Here is another example of the conservation of momentum. DR. Smith has a column of four rubber balls each on top of the other with the heaviest on the bottom and the lightest on top. He is going to transfer the momentum from the bouncing heavier ball on the bottom to the lightest ball on the top! When the momentum gets transferred the ball on top goes shooting straight up! There is always friction so some momentum is lost to that, but definitely a lot of momentum does get transferred to the light ball!
the conservation of momentum can also be illustrated with a basketball and a tennis ball. Transferring momentum from a bouncing basketball to a tennis ball is as easy as dropping them together. The great increase in speed of the tennis ball is the result of the momentum transfer from the basketball!
This is an example of potential energy getting converted to kinetic energy. Dr. Smith is cutting a racquetball in half. Once done he inverts the racquetball half and sets it on the table. there is a lot of energy in the racquetball now due to its position. Energy of position is referred to as potential energy. He then releases this potential energy converting it to energy of motion, or kinetic energy by pushing down on the sides of the racquetball.
(make video and do narration) A working rail gun not only converts potential energy to kinetic energy but also takes advantage of newton’s 3rd law to shoot a steel ball bearing using magnets. Dr. Smith is going to use a total of 13 steel ball bearings, two 24 inch long ½ inch inner diameter PVC pipes, tape measure, 4 neodynium magnets, electrical tape and scissors to make his rail gun. He places the pvc pipes along side one another and attaches the first neodynium magnet 6 inches from the end of the combined pipes. Notice what happens when he aligns three steel bearings on one side of the magnet and rolls a fourth ball bearing toward the other side of the magnet. Potential energy gets converted to kinetic energy as the bearing increases its speed as it gets attracted as it travels toward the magnet. When it strikes the magnet its momentum gets transferred to the last steel bearing which shoots off at a much faster speed than what the initial ball bearing was rolling with. A rail guns takes advantage of this conversion of potential energy of the magnets to kinetic energy of a ball bearing. He is now placing a second neodynium magnet four inches from the first magnet. Check this out, this time when he rolls a bearing toward the combined magnets the final bearing shooting out of the rail gun is even faster. So now he is going to place the 3rd and 4th magnets on the gun again separated by four inches. The combined potential energy of the magnets converts a slowly rolling ball bearing into a bullet! To increase the power of the rail gun make sure the magnets are oriented such that they are attracting one another. You can also increase the length of the PVC tubes and separation of the magnets for increased power.
