Bursting water balloons in zero gravity also looks cool

Don't believe me? It's true.

"What would make this look cooler?"
"I know! Let's put red dye in the water!"

that is quite funky.

Want to know what that looks like in zero gravity? Its practically the same

I've just discovered that explaining the concept of gravity to a 5 year old is quite a challenge.

just pick it up above yr head, and say this is gravity and drop it

You have clearly never interacted with a 5 year old. Even with blood spurting from his head, and a sucking chest wound he'd still say, "but whyyyyyy?"

[katinacooker]

i have actually

i did my work experince in a primary school

i still have nightmares (why would the primary 6-7 girls tie me up with their skipping ropes, and i wish i was joking)

Start off by explaining that each and every piece of matter attracts any other piece of matter with a force which is directly proportional to the sum of their masses and inversely proportional to the square of the distance between them. Once he's got that you can move on to Einstein's general theory of relativity and the curvature of space-time around massive objects, which is where we start really getting to the roots of what gravity is all about.
Explain that a hypothesised particle, the graviton, is responsible for the force of gravity but one has yet to be detected.

Somewhere someone's head has just burst reading that.

i went crosseyed for a bit, but i actually understand most of it

[Fren]

wow

It's actually an interesting idea for a uni project. Using CFD modelling without the gravitational body force in the navier stokes equation. It'd be a nightmare trying to deal with the change in boundary condition during the "bursting" phase.

I miss fluid mechanics, shame I was shit at it. Though in fairness the exam was a pure memory exercise and I had looked at the wrong stuff.

We've got books that explain it on our shelves...I'll throw one at him and see what he says
