3D simulator
Drive Sepang
Drive an original car with 2026-style F1 power around a circuit inspired by Malaysia’s Sepang: two long straights, a hairpin and a twisty infield. Chase a blue rival car: a tow behind it plus overtake mode gets you to 2026 record pace, 360 km/h.
Loads a 3D scene only when you press start. Fast motion on screen.
Steer by dragging the steering wheel round (mouse or finger) and press the Throttle and Brake pedals. PS5 controller: left stick steers, R2 throttle, L2 brake, L1 boost, R1 gear up, Cross gear down, D-pad down to box, D-pad left and right to pick tyres, Triangle camera, Square reset, Create full screen. Keys: ↑ or W accelerate, ↓ or S brake, ← → or A D steer, Space boost (overtake mode), E Q gear up and down (the first shift switches to manual, G back to automatic), P box this lap, 1 2 3 soft, medium or hard tyres, B braking assist, C camera, R reset, Esc exit. Tuck in behind the blue rival on a straight for a tow (the Tow light comes on). An approximate layout inspired by Sepang International Circuit, not an official track model.
Race weekend: hit a barrier and the car bounces off at the angle you hit it, slides and can spin; the front wing breaks first, then the suspension (the car pulls to one side), and a big impact ends in a red flag (Reset gives you a new car). Gravel traps on the outside of the corners slow you down fast. Box for new tyres: the car drives itself down the pit lane at 80 km/h, the crew changes the tyres in about 2.5 seconds (longer with repairs), and you rejoin. Tyres warm up, wear and lose grip; wear runs faster than a real race so a stop comes within a few laps. Your race engineer talks to you on the radio (the voice follows the Sound switch).
How it works like a 2026 F1 car: a 1.6-litre V6 turbo of about 400 kW plus a 350 kW electric motor (MGU-K), an 8-speed gearbox, a 4 MJ battery that the energy manager keeps topped up: it recharges under braking, from engine power the tyres can’t use, and by super-clipping on straights when it is under half full, keeps a 20% reserve for overtake mode, and never wastes power on wheelspin, and active aero that flattens the wings into X-mode on the straights. Power and battery rules follow the FIA 2026 power unit regulations; gear ratios, aero and grip are estimates.
Ready when you are.
Lights out
Hit Start. Five red lights come on one by one, then go out after a random pause. React the moment they go out. Space or Enter works too while React is focused.
A just-for-fun reaction challenge. This is your result, not a real race statistic.

In the garage
The car that jumps.
Jerald is a huge Tesla fan, so the newest dream machine gets a spot in the garage.
- On 15 October 2026, Tesla showed its new Roadster at a SpaceX test site in McGregor, Texas.
- In the demo, an empty car rose off a ramp, flipped in mid-air and landed. Elon Musk said the lift comes from 10 nozzles fed by ultra-high-pressure air tanks, built with SpaceX.
- Tesla claims 0 to 60 mph (about 97 km/h) in under a second and plans production for 2028.
- The flights were short, nobody was inside, and the flying features are not approved for public roads.

03 / Through the lens
Freeze the moment.
Photography is speed, light and timing. Which makes race day the perfect place to point a camera.
Holding history
The world’s most expensive camera
€14.4 million
That is what Leica 0-Series No. 105 sold for at auction in June 2022, including fees. It was Oskar Barnack’s own 1923 prototype, one of the cameras that started 35 mm photography.
Illustration: an original 1920s-style rangefinder inspired by it, not the real camera.
Camera lab
Set the aperture, shutter speed and ISO like a real camera, watch the viewfinder change, then take the shot.

04 / Build lab
Big ideas start with “what if?”
From robots on the ground to rockets in the sky, there’s always something new to figure out.
Aerospace
Rockets and orbits
Launch pads, engines and the long climb to space. Always asking: how does that work?
Robotics
Machines that move
Sensors, motors and code working together. Figuring out how robots see, think and build.
Ideas to try
- Sketch a rover
- Design a moon base
- Invent a helper robot
Starting points for future building sessions, not finished projects.
Launch control
Fly a rocket. Land the booster.
Jerald is the flight director. Poll the room, run the count, throttle down through max-Q, then fly the first stage back down and land it on a ship in the ocean.

Keys (click the screen first): ↑ ↓ throttle, Space hold to burn the landing engine, ← → tilt, P autopilot. On phones, use the on-screen buttons. Land under 6 m/s, upright, on the deck.

Mission log
Max-Q
The moment the air pushes hardest on a climbing rocket: it is going fast, and the air is still thick. Rockets throttle down to get through it, then throttle back up.
MECO and staging
Main engine cutoff, then the first stage lets go. The second stage lights its own engine and carries on to orbit while the booster turns around for home.
The hoverslam
A landing booster can’t hover: even at its lowest throttle its engine pushes more than it weighs. So the burn has to start at just the right moment and reach zero speed exactly at the deck.
Kestrel is an original rocket, not any company’s vehicle. Its masses, thrust and limits are estimates in the range of today’s reusable medium-lift rockets, and the ascent runs at 4x speed.
Flight deck
Take off. Fly the approach. Land it.
Jerald is the captain of the JK Air twin-jet at a big tropical airport. Thrust up, rotate, climb out, then line up on the glide path and grease it onto runway 32 Left. A PS5 controller works too.
3D flight simulator
Fly the JK Air jet
Pick a mission: take off from runway 32 Left and climb to 3,000 ft, or fly the last 7 km of the approach and land. Fly-by-wire keeps the jet from stalling; the landing is up to you.
Loads a 3D scene only when you press start. Sound and voice callouts follow the Sound button.
Keys (click the screen first): ↑ climb, ↓ descend, ← → bank, A D rudder and nosewheel steering, W S thrust (hold S at idle after landing for reverse), F V flaps down and up, G gear, Space brakes, P autopilot, C camera, T time 1x/2x/4x, R restart, Esc exit. On phones, use the stick, thrust lever and buttons on the screen.
PS5 controller: left stick flies (pull back to climb), right stick is the rudder, R2 and L2 move the thrust lever, hold Cross to brake, Triangle gear, D-pad down and up for flaps, L1 autopilot, R1 full thrust (TOGA), Square camera, D-pad left and right for time, Options restart, Circle exit. It rumbles on touchdown and shakes the stick near a stall.
Mission
Checklist
- Full thrust (TOGA)
- Hold the centre line
- Rotate at 145 kt, no tail strike
- Gear up once climbing
- Flaps up above 200 kt
- Climb to 3,000 ft
Flight data
Why it flies
Lift grows with the square of the speed. Slow down and the wing needs a higher angle of attack to hold the jet up, until it stalls. Flaps make the wing bigger and more curved, so it can fly slower for take-off and landing.
The glide path
Jets come down a 3 degree slope, about 300 ft for every nautical mile. Beside the runway, four PAPI lights show it: two white and two red means on the path, more white is too high, more red is too low.
Fly-by-wire
The stick talks to computers, not straight to the control surfaces. Let go and the jet holds its path. Pull too hard at low speed and the protection stops a stall and can push the thrust to full by itself (alpha floor).
The JK Air jet is an original design, not any manufacturer’s aircraft. The airport is inspired by Kuala Lumpur International Airport (KLIA) but is not an accurate map. Weights, thrust and speeds are estimates in the range of a mid-size twin-jet airliner. Just for fun, not flight training.
Tech lab

Train your brain like a driver.
Drivers and athletes train focus the way they train fitness: a little every day. Four short drills, about 10 minutes in total, plus a focus block for homework.
Slow breathing calms your body before a big moment. Breathe in for 4, hold for 4, breathe out for 6. Eight rounds.
