Then open a tab and do something you'd never be allowed to do to a real drawing. Every tool reacts with every other one, because they all work on the same simulated paper. ![Painted illustration of the painter brushing a rainbow watercolour that bleeds into wet paper, with crayons, markers, a paint box and a child's rainbow drawing.]() ### Drawing tools Crayons, coloured pencils, markers, paint and watercolour that bleeds into wet paper. Plus a paint board, stencils, a ruler, a compass and spiral gears. ![Painted illustration of the painter sniffing a lemon behind a counter with ketchup, mustard, honey, an egg, oil, butter, flour, salt, sprinkles and a rolling pin.]() ### [Kitchen]() Ketchup, mustard and honey, eggs, ice cream, chocolate, cooking oil, flour and yeast. Knead dough, let it rise and bake a golden loaf. ![Painted illustration of the painter, goggles on his beret, studying a bottle foaming over in stripes, with red cabbage juice in pink and green glasses and fizzing baking soda.]() ### [Science]() Red cabbage juice, vinegar, baking soda, food colouring, dish soap, milk, secret ink, elephant toothpaste and a cola-and-mints geyser. ![Painted illustration of the painter blowing soap bubbles over a toothpaste stripe, a sponge, soap suds, a spray bottle, cotton buds and a hair dryer.]() ### Bathroom Water, a sponge and paper towel, bleach drops for the safety lesson, and in the full toolbox soap suds, a spray bottle and a hair dryer. ![Painted illustration of the painter sprinkling glitter on a glue star, beside salt on a glue line soaking up blue paint, stickers, ink droppers, a stencil and tape.]() ### [Craft]() Glue and glitter for salt painting, ink drops, and in the full toolbox tape, stickers, stamps, googly eyes and a toothpick for scratch art. ![Painted illustration of the painter watching a line of ants march to a drop of honey through a magnifying glass, with a snail, sprouting cress and a watering can.]() ### Garden Ants that come for the crumbs, free from day one. In the full toolbox: mud, sand, leaves, cress seeds that sprout, a pigeon, a puppy, a cat and a snail. ![Painted illustration of the painter pushing a toy car through blue paint, leaving tyre tracks, beside a monster truck, a beach ball, a football and a marble.]() ### Toy box In the full toolbox: toy cars and a monster truck through wet paint, balls, bubbles, a water pistol and slime. ![Painted illustration of the painter studying a splash of blue ink through a magnifying glass, with a hammer, a squashed marker, a scraper, a ruler, an iron and a bank card.]() ### [Toolbox]() A hammer, a scraper, a paint bucket, an iron, a magnifying glass and fire. The dangerous things stay on the screen. ## Do it on screen, then do it for real A Time tab skips ahead: wait 3 days and mould grows on the food you left, bake the page and the crayon melts into deep colour, freeze it and wet watercolour grows ice ferns, leave it a week in the sun and the colours fade except under whatever was lying on top. On this site every experiment has a second half: how to do the safe version in your own kitchen, with an adult, and why it works. The ones that are never safe at home \(bleach with vinegar, water on burning oil\) stay on the screen, and we say so plainly.

[For parents]()[One honest price]() ## For teachers: the messy lesson without the mess Show melting and freezing, acids and alkalis, mould and decay on the whiteboard, let the class predict, then do the safe version for real. No student accounts and no data, and the browser version runs without an install. Our teacher pages map each experiment to topics such as NGSS 2-PS1-4 \(reversible and irreversible changes\) and KS2 Year 5 "properties and changes of materials". [For teachers]()[Reversible changes lesson]() ![Painted illustration of three children and the painter at a classroom table with red cabbage juice in pink, purple and green glasses and a magnifying glass.]() ## Questions parents ask What is Extreme Drawing? A drawing and painting app by Game Tailors in which the paper behaves like real paper: paint bleeds and dries, food stains and goes mouldy, and pages can be baked, frozen or left in the sun. It also shows real kitchen science, such as red cabbage juice changing colour. What ages is it for? Children of about 4 to 10. Younger children mostly splat, smear and draw; older ones try the experiments and the time skips on purpose. How much does it cost? It's free to start, with no time limit. One optional unlock adds the full toolbox: €5.99 in the eurozone \(local prices in each store\), bought once by a grown-up behind a parent gate. No subscription and no ads. Does it work offline? Yes. The iPhone, iPad and Android apps work without Wi-Fi or mobile data. The browser version needs a connection to load. Is it safe if my child sees fire and bleach in the app? The dangerous things stay on the screen, and the app says why: mixing bleach and vinegar fills the room with chlorine gas and teaches the child to open the window. Our safety pages explain what to do if it happens for real. ## Try it now, no install The browser version has the same tools as the apps. Open it, pick up the crayon, and squeeze some ketchup on your drawing. [Play in your browser]()[iPhone, iPad and Android]() - No account - No ads - Free to start
