This experiment consists of a flask of poison, a radioactive source, a Geiger counter, a sealed box and a mammal from the Felidae family. What is the name of the experiment?
Schrodinger’s cat.

What sign did God give to Noah, promising he would not flood the earth again?
The rainbow.

In ice cream, what ingredient mainly decides how cold it has to get before it fully freezes?
The sugar — the more sugar there is, the lower the freezing temperature.

In 2024, Ray-Ban Meta glasses became hugely popular. What was so special about them?
By wearing the glasses, it was possible to record videos and listen to music.

Older cars, up until around 1990 had carburetors. What substitute is used in modern cars?
Fuel injection system/Fuel injectors

Who is the father of quantum mechanics? (Hint: He won the 1918 Nobel Peace Prize in 1919 and there is a constant named after him in physics…)
Max Planck.

The Bible consists of 66 books. Name at least 5 of them. If you name 7, get double points, if you name 10, get triple points.
Eduards will know.

If the sugar percentage in an ice-cream mix is increased from 14% to 20%, the final product becomes noticeably softer even when frozen at the same temperature. Explain why this happens in terms of freezing-point depression and the balance between ice and unfrozen water.
Sugar lowers the freezing point, so less water turns into ice and more remains liquid. With more unfrozen water, the texture becomes much softer at the same temperature.

Vision from the Marvel Cinematic Universe is a synthetic being and a robot-android with abilities such as changing the density of his body and using an energy beam from the Mind Stone. His body is made of a fictional metal known for its exceptional strength and its ability to absorb vibrations. What metal from the Marvel universe is used for his body?
Vibranium

What’s this? 
A welded differential

In quantum physics, light can behave like a wave and like a particle, depending on how you look at it. What is this idea called?
Wave-particle duality.

What did Moses receive from God on mount Sinai? For double points - where were they later put? Hint: Indiana Jones
The 10 commandments, The arc of the Covenant

This traditional high-fat European ice cream style that became famous in the 19th century and is known for using only real cream, eggs, and sugar — no additives — and later inspired many Soviet-era ice cream standards. What is it called?
Plombir

In 1832, physicist Joseph Plateau invented an interesting device that was a disc with slits and drawings. If you spin this disc quickly and look through the slits, the drawings come to life! What was this device called, and what key principle was it demonstrating about our vision?
Phenakistiscope; Persistence of vision

The mercedes w11 had DAS - Dual Axis steering (Banned since 2021). A system, where by pushing or pulling on the steering wheel you could change the toe of the weel (no toe to toe out). Where and how would this be beneficial?
Neutral toe provides better straight line speeds, even temperature and less tire degredation. Toe out is better for cornering, ensuring better steering response and slip angles

Experimentally, this effect disagrees with classical electromagnetism, beacuse it states that light is a particle, not a wave. What is the name of this effect?
The photoelectric effect.

How many tribes of Israel were there? Hint: Before he was called Israel, his name was Jacob. (+ 50 points for every tribe you can name)
12, The 12 sons of jacob (Reuben, Simeon, Levi, Judah, Dan, Naphtali, Gad, Asher, Issachar, Zebulun, Joseph, and Benjamin)

In professional ice-cream making, the ice cream mix is made of five main components. List the typical percentage range of each: water, sugar, fat and milk-solids. BONUS POINTS: air amount by volume.
Water 60–65%, sugar 12–16%, fat 10–16%, milk-solids 8–11%, air 20–50% by volume.

Classic silent films used a shooting and projection frequency of 16 frames per second. Because of this, viewers often saw an unpleasant flickering effect. Why?
Calculate the minimum refresh rate (in frames per second) that a display must have to avoid flickering for most people (the inertia of vision retains an image for about 50 ms ).
1) At 16 fps, the duration of one frame = 1/16 = 63 ms. This is longer than the visual inertia time (~50 ms), so the brain had time to ‘notice’ the change in the black overlay frame, which caused flickering. 2) 20 frames per second

In quantum computing, this term refers to a machine that doesn’t use only 0s and 1s, but also has the possibilty of being “both in the same time”. What is this term?
A qubit.
