Science Riddles To Test Your Intelligence & Workout Your Mind

we've all came to this world with certain common sense however not everyone possesses exceptional intelligence and a deep understanding of science are you one of the few extremely intelligent individuals on earth let's find out with these five science riddles designed to test your intelligence but also give your brain a workout number five the ice diamond riddle you've got a glass of water and an ice cube now the ice cube contains a diamond inside but you don't know because it's looking clear and shiny then you drop the ice cube in the glass of water and wait for it to melt here comes the interesting part when the ice cube melts and the diamond falls to the bottom of the glass does the water level go up or down or does it stay the same what's your first instinct telling you about this let me know in the comment section down below if you want to think of an answer you've got three seconds to pause this video to give yourself some time to think the answer is the water level goes down that was a tricky one so if you got it wrong listen up for the solution let's start answering this by using Archimedes principle and using water as our fluid of choice any floating object displaces its own weight of fluid in this case water so the weight of the Ice Cube on its own is equal to the weight of the water displaced by the object imagine it's the weight of water fitting into this shaded area here so when the ice cube melts it melts to fill the shaded area I know it sounds strange because the cube is larger in volume than its same weight of water but it's because ice is strange and then it's more dense when it melts water expands when it freezes so a gram of ice has a larger volume than a gram of water now that proves to us that if you put an ice cube in the water by itself when it melts the water level will stay the same and not level up as you first thought up so what about the diamond when the diamond is frozen into the cube it displaces its own weight in water in line with Archimedes principle however when the ice cube melts it falls to the bottom since it's more dense than water but in the water by itself it's only displacing its volume worth of water and not its actual weight it's actual weight inside the ice cube displaces more water than the weight of its volume worth of water when it's at the bottom of the glass that means the water level goes down when it melts number four which switch controls the bulb imagine yourself in a basement you're looking at three light switches in the off position each one controls one of three filament light bulbs on the floor above you're allowed to turn on any of the switches but you can only go upstairs one time how can you tell which switch controls which light bulb pause this video in three seconds if you want to figure out the answer yourself and share with me in the comment section down below the solution is you flip any of the switches on for five minutes afterwards turn off that switch and quickly flip another switch on and go upstairs touch the two lights that are off one will remain hot because it was on for five minutes notice I said filament lightbulbs additional energy is released as heat when lit up so you can use that to your advantage so obviously the hot bulb is controlled by the first switch you turned on easy right the light that's currently on is under the control of the switch you last flipped on and the cold bulb that's off is controlled by the switch you left untouched number three the virus riddle imagine yourself with a research group discovering a prehistoric virus and isolating it for further research and examination after working all night long you're closing the lab when suddenly an earthquake hits and knocks out the power the emergency generator kicks into action and the alarm confirms an emergency all your fears are about to come true the deadly airborne virus you have found is contained for now but it's about to get released into the world through vents that will soon open unless you can destroy it imagine the lab is a four by four grid with 16 rooms now imagine that the entrance room is at the northwest corner and the exit room sits at the southeast corner the virus is released in each room except in the entrance room to destroy the virus you have to enter each room and pull a self-destructive switch that will destroy the virus along with the room itself but there's a catch you can't reinter a contaminated room after exiting it since to exit it you've activated the self-destruct switch putting the room in a lockdown mode here's the challenge you have to enter the entrance room exit through the exit room and destroy the ancient virus you found how would you do it let me know in the comment section down below here's a brief summary of the rules explained you've got a few seconds to pause the video if you want longer to think of a solution yourself now for the explanation the truth is you can't get to the exit and enter every room without backtracking at all you may have started graphing your route in every possible way and this is the correct way to solve it but without thinking outside the box it's impossible since it's related to the Hamiltonian path problem basically no Hamiltonian path a path that visits every single point exists for this problem but if you looked at the rules carefully you would have noticed an important exception that will enable you to solve this puzzle there is a room you can enter two times and that's the entrance since it doesn't have a self destruction switch it's not locked down like the rest of the rooms so you can leave and come back and enter the other door this is how you visit all of the rooms and get to the exit is this the solution you came up with - there are eight different options for a successful route four for each of the two different starting rooms so if you figured it out you did a great job number two the bol riddle let's warm up with a simple bowl rattle before a harder one take two coins identical in weight and two buckets filled with the same amount of water the first bucket of water is 25 degrees Celsius and then the other one the water is 25 degrees Fahrenheit imagine tossing each coin in each bucket at the same time when dropped which coin will hit the bottom first pause this video now if you want to figure out the answer for yourself the answer is the coin in the 25 degrees Celsius bucket will hit the bottom first because the other bucket of water is frozen 25 degrees Fahrenheit is below freezing which for water is 32 degrees Fahrenheit so that bucket is filled with ice now let's continue with something more complex than this brace yourself so imagine holding a bowl of water you put a ball with a sensor inside the middle of the water in the bowl at the bottom of the bowl there's a sensor - your challenge is you need to get the sensor at the bottom of the ball and the one at the bottom of the bowl to touch the ball floats and for some unimportant reason you cannot remove the water from the ball you also cannot touch the ball with your hands or any other object easy task you think how will you push the ball at the bottom without touching it or removing the water from the bowl confused already you've got a few seconds to pause the video if you want longer to think about the solution here's how it's done take an empty glass and put it on top of the ball without touching it the air inside the glass will push down the bolts of the very bottom so when you push the glass down the water level beneath it goes down because the air trapped in the glass cannot escape so the ball floats on the water at the bottom of the glass until it reaches the bottom of the bolt pretty amazing right number one the boat riddle imagine you're in a boat the boat is floating in a lake with a rock in it you toss the rock off the boat end of the lake what will happen to the water level will it go down or up or maybe stay the same armed with previous knowledge you should be able to solve this one you've got a few seconds to pause the video if you need longer to think about it here's the answer the water level will fall you again turn to Archimedes principle which states that the buoyant force on an object submerged in the water is equal to the weight of the volume of water that object displaces this is one way to solve this riddle another way is to consider an extreme case imagine an extreme case where rock is very heavy but also very small like a black hole rock imagine putting that rock in a boat the boat will sink very low in the water to compensate meaning it pushes the water level up if you take the rock off the boat the boat will displace much less water and the water level will go back down so if you drop the rock into the water because of its small size the water level won't rise but go down easy is that while in the boat the rock was displacing its own weight however in the water it was displacing its own volume if the rock is denser than water the amount of water displaces when it floats is higher than the amount of water in place of its volume when it sinks so it displaces less water when it's actually in the water and the level goes down so how many of these riddles did you answer successfully let me know in the comment section down below and keeping to the science theme if you've ever wondered what happens if you stand in the Hadron Collider while it's on you should click on the video on screen now thanks for watching you
