AYE.GG / PARTICLE LAB
Build a world. Pour something in. See what happens.
Changed scenes save separately every 30 seconds while visible, and when leaving the page if possible.
LIVE BIOLOGY
Seeds need moist soil, air and mild conditions. Load the garden to watch the whole cycle.
LIVE ENGINEERING
Add a Battery or an uncovered Solar cell, then join it to a device with Wire.
LIVE SCIENCE
When the simulation detects a modeled change, it records what appeared, a real relationship or equation, and what the pixels cannot prove.
Spawn near the drawing cursor. Acceleration, braking, gravity and swept terrain collisions are modeled. Liquids slow movement; tap Jump / swim repeatedly for separate strokes. Buoyancy, calibrated viscosity and chemical injury are not modeled. Position is temporary. Inspect cell identifies a placed element or token.
Garden ready. Seeds sit on moist soil. Keep the simulation running to watch stems grow; fertilizer-fed plants grow faster. Turn daylight off to compare.
One pointer owns each brush, line, box or pan gesture. An unfinished line or box is cancelled when you use Undo, change tools, brush size or view, replace the scene, pause or step, use canvas keys, or leave the canvas/page. A cancelled preview keeps your earlier Undo; a completed shape or uninterrupted brush stroke is one world Undo. Already-painted cells remain until you undo or replace them. Losing pointer capture or releasing the button stops input, and a failed capture makes no edit. Start a fresh gesture to continue; use Zoom and Pan rather than pinch gestures. These safeguards do not change the simulation rules.
Load movement course replaces the lab with an editable dry hurdle, water pool and exit hurdle, starts paused at normal speed and spawns the figure on the left. Undo restores your previous world. Resume, focus the canvas and use Left/Right or A/D to build speed; release to brake. Air steering is weaker than ground steering. Press Up, W or Space to jump from ground. In liquid, release and press again for another upward swim stroke; holding the button does not repeat jumps or strokes. Touch buttons use the same rules. Water slows both horizontal motion and falling; gases do not act as liquid drag. Materials are not displaced by the figure. The model has no buoyancy, measured viscosity, drowning, heat or chemical injury, and uses game cells/ticks rather than real units. A figure buried by an edit stops until you erase space or reset it. Character state is temporary and excluded from backups.
Recovery autosave stores a changed scene separately every 30 seconds while the page is visible and tries again when you leave. A valid recovery opens paused on your next visit when autosave is enabled. Restore recovery also pauses and gives you Undo to the previous world. Turn the checkbox off to stop automatic writes and automatic startup recovery; your previous recovery remains available. The manual Save scene slot stays separate. Recovery keeps the same world data as a file backup, not the temporary character or notebook. Browser settings, storage limits or a sudden crash can prevent saving; export important builds to a file. This is device-local recovery, not cloud sync.
Export scene downloads a JSON backup of your materials, ages, switch states, moisture, nutrients, growth and daylight. Import scene accepts a validated aye.gg scene file up to 5 MB and starts paused, so you can inspect it before pressing Resume. If you draw, step, resume, change daylight or replace the laboratory while a file is reading, that import is cancelled and your newer scene and playback are kept. Selecting another file supersedes earlier reads; late results cannot overwrite the newer selection. View-only zoom and pan do not cancel a file. Undo restores the world from before a successful import. Your browser Save scene slot is not replaced. The temporary stick figure, notebook, camera and playback speed are not included. Scene files contain data, not scripts; unsupported or malformed files leave the current world intact. Keep your own copies: this is a local file backup, not cloud sync.
Place seeds on moist soil with air around them. A seed first forms a visible sprout and root; roots move water and nutrients upward while daylight or a powered lamp supports stems and leaves. Compost or fertilizer in wet soil speeds later growth. Mature stems form flowers, then fruit that falls and eventually leaves a new seed. Darkness holds sprouts before stem growth, and flooding can block germination.
Open Bubbles & metals. Vinegar and baking soda produce CO₂ on the left; zinc and dilute HCl produce H₂ in the middle; copper stays intact in HCl on the right. Limestone also bubbles in acid. Inert gases do not burn, while oxygen supports combustion.
Search the palette by name or formula: seed, pump, Fe, H2O or CO2. Material view can show behavior materials and tools or reference tokens separately. Search narrows that view. Clear resets both search and view to every choice; Enter selects a single match and returns to the canvas. In Chemical table, search by name, symbol or atomic number, such as iron, Fe or 26. Element results open details; compound results select a material. Reference-only elements stay reference-only. Filtering never changes the active brush, rewrites the world or removes elements from the Chemical table. A paused unfinished drawing gesture is cancelled when the view changes; finish or release it before filtering.
Pour water onto magma. Contact turns magma into stone and water into rising steam. Carve channels with Erase to guide the flow.
Pour sand, water and oil into a stone bowl. Sand sinks, water settles below oil, and salt dissolves into a denser saltwater layer.
Melt ice with magma, make smoke by burning coal or wood, and compare HCl against iron, copper and glass. The reactions are simplified game rules.
Place a powered house, greenhouse, pump station, factory line, solar garden or solar smart greenhouse, then rebuild it. Every blueprint uses editable materials and machine parts from the Element table. The live machine monitor counts active sources, powered devices, live wires, closed switches and triggered sensors so broken connections are visible instead of guessed.
Keep a solar cell clear, connect it through wire and a closed switch, then run a freezer, magnet, lamp or sprinkler. The smart greenhouse uses one solar source, two lamps and two water-fed sprinklers. Cover the cell or turn off Daylight to interrupt the whole circuit.
Compare five separated tests: magnesium releases hydrogen in dilute HCl; silver stays intact; sodium hydroxide neutralizes HCl; and universal indicator changes red beside acid, green beside water or neutral reaction solution, and blue beside base. The balanced classroom equations are Mg + 2HCl → MgCl₂ + H₂ and HCl + NaOH → NaCl + H₂O. Pixel amounts, pH and reaction rates are not measured.
Open Element behavior gallery. Neon rises while denser argon sinks; both stay inert. Aluminium conducts and releases hydrogen beside modeled dilute HCl, while gold and silicon stay intact. Sulfur beside fire or magma forms visible, dense sulfur dioxide. The gallery compares qualitative relationships, not laboratory amounts or safe procedures.
Science references: seed germination · vinegar and baking soda · magnesium and HCl · acid–base neutralization · iron corrosion · lithium, sodium and potassium with water · calcium and water · nickel · neon · aluminium · silicon · sulfur · argon · gold. These sources support the qualitative properties, not the game timing or pixel quantities. Never copy these simplified game reactions into a real experiment.
