25. Festival bracelet

  • Hilarious Heureka moment

    Can a festival bracelet be made into handcuffs? Of course not. Or can they? You'll find out in the video.

24. Ghost Soap Bubbles

  • Science facts from the video

    The experiment combines chemistry and physics in a spectacular way. When carbon dioxide ice is added to a suction flask containing hot water, it begins to sublimate - that is, to change directly from solid carbon dioxide to gas.

    A hand held over the mouth of the flask prevents the gas from escaping, causing pressure to build up inside the flask. At the same time, the end of a tube is dipped into soapy water in a petri dish. When the tube is lifted out of the liquid, the carbon dioxide escapes and stretches the soap film into a bubble. Bubbles are created as a result of the pressure difference: the gas tries to equalize the difference between the flask and the environment.

23. Heirloom deathblow

  • Science facts from the video

    The experiment is based on a classic trick performed by magicians, in which the ring due to the influence of gravity spins in time and remains hanging on the chain. In the version shown in the video, unlike the traditional version, the tire also has a small gap through which the chain can partially pass through and the tire seems to go through the chain.

    For example, magicians use the laws of physics combined with movement that is too fast for the eye to perceive. Depending on the metal, its melting point can vary surprisingly much.

    For example, mercury already melts at -39 °C and gallium at 30 °C.

22. Western of the month: Toilet paper duel

  • Science facts from the video

    The amazing trajectory of the toilet paper is based on the Bernoulli effect. According to Bernoulli's law, the pressure of a fluid, in this case air, decreases as its velocity increases. In the experiment, a negative pressure is created above the toilet paper roll, which lifts the toilet paper upwards and makes it fly a longer distance. As can be seen in the experiment, the Bernoulli effect is stronger the higher the air speed.

21. Reindeer à la Heureka (potato chip vs. teddy bear candy)

  • Science facts from the video

    Potato chips burn surprisingly well and would be perfect for lighting a campfire. The dry potato in the potato chip ignites easily with the abundant fat in the chip, creating a handsome flame. In the case of the teddy bear candy, potassium chlorate decomposes at high temperature into potassium perchlorate and further into oxygen. At the same time, the sugar and other flammable substances in the teddy bear candy oxidize strongly, creating a beautiful flame. The end products are a lot of heat, potassium chloride as a product of the decomposition of potassium chlorate, and carbon dioxide and water from the oxidation of sugar. How much energy there is in these little treats!
