Magic Tracks is a popular toy that combines the fun of racing cars with the excitement of magic. It features a glow-in-the-dark racetrack that can be easily assembled and creates endless possibilities for play. The set comes with remote-controlled cars that can zoom through the track with ease. One of the standout features of Magic Tracks is its flexibility. The pieces of the track are designed to snap together, allowing kids to create different track configurations and designs. This enables them to experiment with different layouts and challenge themselves to create the most exciting and challenging courses.
The team came across "magic," which is a mathematical measure of how difficult a quantum state is to simulate using an ordinary classical (non-quantum) computer. Their calculations showed that in a chaotic system almost any state will evolve into one that is "maximally magical"—the most difficult to simulate.
This notion received a boost in the 1990s, when theoretical physicist Juan Maldacena related the gravitational theory that governs spacetime to a theory involving quantum particles. But just considering the degree of entanglement on the boundary cannot explain all the properties of black holes, for instance, how their interiors can grow, says Goto.

Designed with LED lights, these cars glow as they race around the track, creating a mesmerizing sight in the dark.
Quantum 'magic' could help explain the origin of spacetime
A quantum property dubbed "magic" could be the key to explaining how space and time emerged, a new mathematical analysis by three RIKEN physicists suggests. The research is published in the journal Physical Review D.
It's hard to conceive of anything more basic than the fabric of spacetime that underpins the universe, but theoretical physicists have been questioning this assumption. "Physicists have long been fascinated about the possibility that space and time are not fundamental, but rather are derived from something deeper," says Kanato Goto of the RIKEN Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS).
This notion received a boost in the 1990s, when theoretical physicist Juan Maldacena related the gravitational theory that governs spacetime to a theory involving quantum particles. In particular, he imagined a hypothetical space—which can be pictured as being enclosed in something like an infinite soup can, or "bulk"—holding objects like black holes that are acted on by gravity. Maldacena also imagined particles moving on the surface of the can, controlled by quantum mechanics. He realized that mathematically a quantum theory used to describe the particles on the boundary is equivalent to a gravitational theory describing the black holes and spacetime inside the bulk.
"This relationship indicates that spacetime itself does not exist fundamentally, but emerges from some quantum nature," says Goto. "Physicists are trying to understand the quantum property that is key."
The original thought was that quantum entanglement—which links particles no matter how far they are separated—was the most important factor: the more entangled particles on the boundary are, the smoother the spacetime within the bulk.
"But just considering the degree of entanglement on the boundary cannot explain all the properties of black holes, for instance, how their interiors can grow," says Goto.
So Goto and iTHEMS colleagues Tomoki Nosaka and Masahiro Nozaki searched for another quantum quantity that could apply to the boundary system and could also be mapped to the bulk to describe black holes more fully. In particular, they noted that black holes have a chaotic characteristic that needs to be described.
"When you throw something into a black hole, information about it gets scrambled and cannot be recovered," says Goto. "This scrambling is a manifestation of chaos."
The team came across "magic," which is a mathematical measure of how difficult a quantum state is to simulate using an ordinary classical (non-quantum) computer. Their calculations showed that in a chaotic system almost any state will evolve into one that is "maximally magical"—the most difficult to simulate.
This provides the first direct link between the quantum property of magic and the chaotic nature of black holes. "This finding suggests that magic is strongly involved in the emergence of spacetime," says Goto.

The remote control allows children to control the speed and direction of the cars, adding an element of competition and excitement to the play experience. Another advantage of Magic Tracks is its durability. The track pieces are made from a flexible and durable material that can withstand the rough handling of young children. This ensures that the track will last for a long time and can be enjoyed by multiple generations of children. Magic Tracks also encourages imagination and creativity. Children can create their own races, set up obstacles, and even make up their own rules for the game. This allows for open-ended play and provides ample opportunities for kids to use their creativity and problem-solving skills. In summary, Magic Tracks is a toy that combines the thrill of racing cars with the enchantment of magic. With its flexible track design, remote-controlled cars, and glow-in-the-dark features, it provides endless entertainment and encourages creativity and imagination. It is a toy that can be enjoyed by children of all ages and is sure to provide hours of fun..
Reviews for "Unleash Your Inner Racer with Remote Control Magic Tracks Cars"
1. Sarah - 1 star
I was really disappointed with the Magic Tracks Cars with Remote. The cars didn't work as smoothly as advertised, and they kept getting stuck on the track. The remote control was also very flimsy and stopped working after just a few uses. Overall, it was a waste of money and I wouldn't recommend it.
2. John - 2 stars
I purchased the Magic Tracks Cars with Remote for my son's birthday, but it ended up being a big disappointment. The cars would often derail from the tracks and were difficult to put back on without adult help. The remote control was not user-friendly and my son quickly lost interest in playing with it. It's a shame because the concept seemed great, but the execution was poor.
3. Emily - 1 star
Magic Tracks Cars with Remote turned out to be a complete disappointment. The cars would constantly get stuck on the tracks and the wheels would come off easily. The remote control had limited functionality and the batteries ran out quickly. My kids lost interest in playing with it after just a few days. I would not recommend this product to anyone.
4. Mike - 2 stars
I was excited to get the Magic Tracks Cars with Remote for my nephew, but it didn't live up to my expectations. The cars would frequently veer off the tracks and the remote control had a very short range. The build quality was also not very good, as one of the cars broke within a week of use. It was disappointing overall and I wouldn't purchase it again.
