12 Most Satisfying 2D Simulations | 9 Minutes of Pure Satisfaction

12 simulations, one rule each. Every collision plays a note — there is no music track, all of the sound is the physics. Every rule in this video came from your comments. 0:00 The bomb passes on touch — whoever holds it at zero explodes 0:47 Cells divide on their own — one ball eats them and speeds up 1:34 Every bounce it grows, and copies itself 2:21 Every bounce rolls a 5% chance — heads a ball, tails a square 3:08 Hit the wall and a square splits into three 3:55 Equal numbers merge and double 4:42 Touch the white ball and you turn rainbow 5:29 Each circle eaten spawns two more — the square starves if it stops 6:16 When two rectangles touch they merge, and a fresh pair drops in 7:03 Opposite colours pull together, same colours push apart 7:50 Hit the gold wall: gain a side. Hit the blue wall: lose one 8:37 Two galaxies, one gravity — they end up as a single disc 9:24 End card Photosensitivity note: contains flashing and rapid colour changes. Which one was your favourite, and what should I simulate next? Best idea in the comments gets built. #satisfying #simulation #physics #asmr #oddlysatisfying
