If you want to google your way out of it start with something like "CSS 2d transform".
There's a lot of differents technologies going on in the background, but it still fairly simple to understand.
1. I parse the the html to wrap each character in a <particle> tag. + Some hacks, to keep withespace.
2. I iterate trough all <particle> element and add velocity depending of bomb position.
3. Velocity is calculated with basic trigonometry. I then move the particules with css 2d transform.
ps. I putted a lot of effort in optimisation, no Math.sqrt, no objects in the loop (velocityX vs velocity.x), etc. But at the end the bottleneck is really the browser rendering.
What I don't understand is how do you manipulate letters like that? I always though font was this static thing that cannot be manipulated. This is mind opening. I am really interested and want to learn more about this. What technology is allowing you to grab a letter and just randomly blow it away?
