Bernoulli's principle - physics experiment
Bernoulli's principle - physics experiment
http://www.fizik.si Physics experiments showing Bernoulli's principle. With the increase of the fluid's speed the pressure decreases.
Preschool science activity
Preschool science activity
http://www.fizik.si An experiment that can be used for explaining basic mathematical operations to children. Already in the kindergarten children can learn some mathematical basics with such didactical tools. The lever is in horizontal balance, if the total torque of the weights on the left side is...
Buoyancy-cool science experiment
Buoyancy-cool science experiment
http://www.fizik.si Buoyancy-cool science experiment This video shows how the melting of ice changes the buoyancy force on the ice cube. Ice cube melting reduces their buoyancy and gravity is dominated force until a drop of water drops from the cube. At this point the lift force is greater than the...
Quicksilver - Science experiment
Quicksilver - Science experiment
http://www.fizik.si Another experiment with quicksilver. Iron or steel object float on quicksilver surface because of its high density. The density of quicksilver is 13,5 kg/dm3.
Floating bubble
Floating bubble
http://www.fizik.si Chemical reaction between vinegar and soda bicarbonate produces CO2, which is densier then air and stays on the bottom of the container. Soap bubbles float in the container with CO2, because the buoyancy on the bubbles is higher as when they float in air.
Soap bubbles and CO2 - Science experiment
Soap bubbles and CO2 - Science experiment
http://www.fizik.si Soap bubbles float in the box filled with carbon dioxide (CO2). CO2 has higer density as air so the buoyancy on the bubbles is higher.
CO2 vs He balloon bang
CO2 vs He balloon bang
http://www.fizik.si Balloons filled with different gases have different bangs. We made a bang comparison between a ballon filled with carbon dioxide and a balloon filled with helium. Helium ballons are the one on the ceiling.
Bubble in a bubble
Bubble in a bubble
http://www.fizik.si A simple trick how to make a soap bubble inside a bigger bubble.

Giant soap bubbles - Science experiment
http://www.fizik.si Soap bubbles can be huge!
How Inhaling SF6 Affects Our Voice
How Inhaling SF6 Affects Our Voice
http://www.fizik.si SF6 gas is six times denser than air. Listen how it changes our voice when inhaled. Slovenian version
Balloons and sound
Balloons and sound
http://www.fizik.si Does the sound produced during the bang depend on gas it contains? (is the BANG sound different?).
Helium flow - Science experiment
Helium flow - Science experiment
http://www.fizik.si Helium flows up in a gutter and blows up the candle. Helium is like all gases a fluid as are also all liquids.
Helium and soap bubbles - Science experiment
Helium and soap bubbles - Science experiment
http://www.fizik.si Soap bubbles are filled with helium. Because helium has lower density as air, the total mass of bubble decreases (relative to soap bubble filled with air) and the buoyancy causes balloon to lift up.
Balloons and acceleration - Science experiment
Balloons and acceleration - Science experiment
http://www.fizik.si There are two baloons in the box. The red one is filled with air and is attached to the top of the box, the white one with helium is attached to the bottom of the box. As the box is accelerated, ballons move in the opposite direction. The air baloon moves in the opposite directio...
Hydrophobic coating - Science experiment
Hydrophobic coating - Science experiment
http://www.fizik.si Hand and the card are covered with superhydrophobic aerogel powder. Layer of air between the water and paper - hand, produce an effect of silver foil. Hand and paper does not get wet.
Aerogel powder - superhydrophobic
Aerogel powder - superhydrophobic "neverwet" coating - Science experiment
http://www.fizik.si Superhydrophobic coating can be a lot of fun.
Water drops on superhydrophobic surface - surface tension - physics experiment
Water drops on superhydrophobic surface - surface tension - physics experiment
http://www.fizik.si This video demonstrates the wonderful and intriguing behavior exhibited by water when it is dripped on paper that is coated with "superhydrophobic" aerogel powder. The water forms tiny marbles and races around like it's on a griddle. Video shows how the detergent reduces the sur...
Relative motion - physics experiment
Relative motion - physics experiment
http://www.fizik.si All motion is relative to the observer or to some fixed object. This is physics experiment for science project. http://www.fizik.si Gibanje je relativno. To pomeni, da se telo giblje samo v razmerju do nekega drugega telesa, za katerega predpostavljamo, da miruje.
The use of strobe light to measure RPM - physics experiment
The use of strobe light to measure RPM - physics experiment
http://www.fizik.si We can measure the frequency of rotation with the help of strobe light. When the strobe light frequency is equal to the frequency of rotation, the body seemingly standstill. This is physics experiment for science project. http://www.fizik.si Frekvenco vrtenja vrtečega se tele...
Polarizer and colours - Science experiment
Polarizer and colours - Science experiment
http://www.fizik.si On the color wheel are palced polarizers at different angles. By rotating the upper polarizer we create an interesting effect
