Bernoulli Effect0 viewsWhen a ping pong ball is placed in a funnel with the air blowing out, the ball won't fall out of the funnel. WHY NOT?Sep 15, 2017
|
|
Newton's 3rd Law: Equal & Opposite Actions0 viewsWagon: The force of the escaping gas from the fire extinguisher accelerates the person on the cart. If the gases exit the fire extinguisher to the right, WHY does the cart go to the left?Sep 15, 2017

Van de Graff Generator0 viewsVacuum Jar #2: The air pockets in shaving cream will expand in a vacuum. So WHY does the shaving cream get bigger?Sep 15, 2017
|
|
Vacuum Bell Jar & Pressure0 viewsVacuum Jar #1: When in the atmosphere, the globe experiences a buoyancy force upward exerted by air. WHY does the globe seem to weigh more when the air is taken out of the bell jar?Sep 15, 2017
|
|
Shaving Cream Puzzle0 viewsVacuum Jar #2: The air pockets in shaving cream will expand in a vacuum. So WHY does the shaving cream get bigger?Sep 15, 2017
|
|
Centripetal Motion0 viewsRotation: Due to the conservation of angular momentum, when the rotating person brings his arms closer to his body, he will rotate faster. WHY?Sep 15, 2017
|
|
Kinetic & Potential Energy0 viewsRoller Coaster: At various points on the track, the car will have the same total energy, but it will be split into kinetic and potential energies dependent on its height and velocity. The higher the PE, the lower the KE and vice versa.Sep 15, 2017
|
|
Roller Blade Puzzle0 viewsRoller Blades: This demo is a combination of explosive collisions and inelastic collisions. Each roller blader gains momentum with each toss AND catch of the pillow.Sep 15, 2017
|
|
Marshmallow Man & Pressure0 viewsAs air is removed from the bell jar, changes occur in the marshmallow man. What do you think will happen?Sep 15, 2017
|
|
Air Pressure0 viewsCan Crusher: A small amount of water is heated in a soda can until steaming. The can is then quickly put in cool water, mouth side down. WHY does the can collapse? And, why did they need to heat water in the soda can to make this demonstration work?Sep 15, 2017
|
|
Momentum0 viewsMomentum Balls: In this case, the momentum of the large ball is transferred to balls at the end. WHY does the last ball go out so far to the right?Sep 15, 2017
|
|
Gravity & Two Trajectories0 viewsCannon Ball: The falling target experiences the same vertical acceleration as a ball launched from a cannon aimed at it. If released at the same time WHY do they hit?Sep 15, 2017

|
Kinetic Energy0 viewsLoop: The ball begins at the top to the right with "potential energy." WHY does it have enough energy to complete the loop without falling down?Sep 15, 2017
|
|
Inelastic Collisions #10 viewsInelastic Cars: In all cases, the two carts stuck together after the collision will have a momentum that is equal to the combined momentum of the two carts before the collision. WHY?Sep 15, 2017
|
|
Center of Mass0 viewsHorse Balance: Look at the wire extending from where the front legs of the horse should be to back behind the rear legs. Now notice that the toy horse is balanced on its rear legs. WHY?Sep 15, 2017
|
|
Air Pressure0 viewsWater Cylinder: An index card is placed on top of a cylinder full of water. The cylinder is then inverted. WHY doesn't the water pour out?Sep 15, 2017
|
|
Inelastic Collisions #20 viewsOne cart is at rest when another cart of equal mass hits it. WHY does the cart on the right move away at an equal speed?Sep 15, 2017
|
|
Gravity0 viewsGravity Balls: One ball, having only a gravitational force, will fall straight down. The other ball, having gravity and a horizontal force, will follow a parabola. Watch it in slow motion. WHY do they hit the surface at the same time?Sep 15, 2017
|
|
Air Pressure0 viewsFlexible Membrane: There is a flexible membrane at the top of the cylinder. When the demonstrator puts his hand on the top of the cylinder, the "diver" sinks. When he takes his hand away, the diver rises to the surface. WHY?Sep 15, 2017
|
|
Pendulum Motion0 viewsA pendulum can never have more energy than what was originally put into the system. WHY doesn't the bowling ball hit the person?Sep 15, 2017
|
|
Centripetal Acceleration0 viewsThe bucket (and water contained therein) experiences centripetal acceleration when swung in a circle. WHY doesn't the demonstrator get wet? (or, WHY doesn't the water fall out of the bucket?)Sep 15, 2017
|
|
Center of Mass0 viewsOnly the center of mass of an object needs to be supported in order to support the object. WHY can you balance the bird so far back?Sep 15, 2017
