Because it doesn't just roll from top to bottom. No, it passes through switches and thus changes its path again and again, it has to negotiate multiple loops, seesaws, rapid descents and tight bends - only to end up in an elevator that transports it back up by itself. From there, their action-packed ride starts all over again.\u003cbr\u003e\u003cbr\u003eThe marble roller coaster comes to your home as a complete kit. Apart from a pair of side cutters (scissors will do in a pinch), you don't need any other tools. Putting it together is not something that can be done in a few simple steps, but is quite demanding and requires some skill, time and leisure, which is why the marble roller coaster is only suitable for young people aged 15 and over. \u003cbr\u003e\u003cbr\u003eAll tracks come with detailed illustrated instructions that are very easy to follow. The instructions for the middle marble roller coaster are in English.\u003cbr\u003eOf course, it is also possible to let your imagination run wild and assemble the marble roller coaster according to your own wishes.

This anti-stress and skill game uses the laws of physics to give you the feeling that you can control time and slow down gravity at the same time. Sounds like black magic at first, doesn't it?

But as soon as you drop the ball into one of the cylinders, you'll be amazed: Instead of simply falling through, the ball glides almost majestically and slowly through the aluminum tunnel.

With a little practice, you'll soon be juggling the ball as if you were a born juggler!\u003cbr\u003e\u003cbr\u003e\u003cb\u003eBut why does the ball defy gravity?\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003eWell, it's made of neodymium, so it's an extremely strong magnet. If you drop this magnet into the aluminum cylinder, this causes a change in the magnetic field inside it. According to Faraday induction, this creates a voltage, also known as electromotive force. The eddy currents it induces generate another magnetic field. This is where \u003cb\u003eLenz's rule\u003c\/b\u003e comes into effect.

Apart from the deep sea, the only thing we can still explore is space. But what does \"only\" mean here? After all, we're talking about infinite expanses ;) But before we can one day colonize other planets or meet aliens, we still have to improve our rocket technology quite a bit. And that's where you come in!\u003cbr\u003e\u003cbr\u003eWith the \u003cb\u003eWaterrokit bottle rocket set\u003c\/b\u003e, you can build your own flyable rocket! The assembly is very simple: you take a plastic bottle, fill it with the specified amount of water, screw on the Waterrokit screw cap with the fins and start pumping air inside using a bicycle pump. As soon as enough pressure has been built up, the rocket is shot meters into the air by a fountain of water. And don't worry, both the screw cap and the valve on the air hose are standardized so that they fit commercially available bottles and air pumps. And if you want to carry out even more exciting experiments with your Waterrokit rocket, you can find tips and tricks in the \u003ca href=\"\/en\/products\/rokit-flaschenraketen-experimentierbuch\"\u003eRokit experiment book\u003c\/a\u003e to get the most out of the rocket.\u003cbr\u003e\u003cbr\u003eWe would like to expressly point out that the rocket is intended for outdoor use only and is not a children's toy.","brand":"Hinterland","offers":[{"title":"Default Title","offer_id":54417059053836,"sku":"22785","price":18.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0684\/8793\/8316\/files\/productImage-22785-water-rokit-flaschenraketen-set-special-nasa-edition.jpg?v=1753867076"},{"product_id":"pi-kuchen","title":"Pi cake","description":"Two things are infinite: the number of decimal places of the number Pi and the average nerd's hunger for sweets and pastries.

She likes to get a little drunk and is therefore always a bit drunk. But as soon as she joins a group, she always creates a good atmosphere with exciting stories.\u003c\/li\u003e \u003cbr\u003e\u003cli\u003e \u003cb\u003eDietmar DIL 8 IC\u003c\/b\u003e is definitely not one of those new-fangled button cells that only flash up briefly and then disappear again; it is a relic from a time when components still had character and microcontrollers were proudly enthroned on the breadboard. He used to call the shots in old synthesizers - today he enjoys the peace and quiet on the sofa with a glass of isopropanol and the chip tune playlist from his best days. And when things get dicey, he always keeps his footing despite his eight legs.\u003c\/li\u003e \u003cbr\u003e\u003cli\u003e \u003cb\u003eWilli Widerstand\u003c\/b\u003e always remains steadfast despite the tension. You can burn out with him, but never burn out. He stands for the classic \"perseverance\" mentality among battery types: never too much, never too little, but just right. Formerly at home in radios, today in retro game consoles, it proudly wears its colored rings like others wear their tattoos. A true classic that knows how to keep energy in check - and looks damn good doing it. \u003c\/li\u003e \u003c\/ul\u003e\u003cbr\u003eAll electronic plushes are house-trained and if someone spills while eating, you can wash them by hand at 30 degrees.

Whether as a decorative highlight or as an introduction to the world of STEM subjects: this gadget is more than just a gimmick.\u003cbr\u003e\u003cbr\u003eThe principle is quickly explained, but all the more fascinating: there are colorful LEDs between a normal mirror (100?% reflection) and a semi-transparent mirror at the front (50?% reflection \/ 50?% transmission). Their light is reflected between the mirrors, while some of it penetrates to the outside - creating the illusion of an infinitely deep tunnel of light points for the viewer. The effect is particularly impressive in the dark and can be operated with batteries or a mains adapter.\u003cbr\u003e\u003cbr\u003eThe 23?cm Infinity Mirror is ideal for children aged 3 and over, but also works as a stylish decorative object on a desk or wall (suspension available).
