Tweenbots are human-dependent robots that navigate the city with the help of pedestrians they encounter. Rolling at a constant speed, in a straight line, Tweenbots have a destination displayed on a flag, and rely on people they meet to read this flag and to aim them in the right direction to reach their goal.
Surprisingly they actually do pretty well, and the video is well worth watching if you have a couple minutes!
So what I’m going to show now in an experiment, is this. Right here I have a glass. [Holding up pint glass.] This glass represents a vagina. What I have this here [holding up sieve], this is a condom.
Because a condom is kind of like a filter. And really small things can get through there, like viruses, right?
And this here is some cream [holds up box of milk or cream] that’s past its sell-by date, so there’s a lot of lumps in it, and there’s also some liquid cream, right? So the lumps will represent the sperm cells and the cream will represent the AIDS virus. So the drops of cream because they are smaller–right now we’re gonna go, this is the penis, right?
So now we’re going to simulate an ejaculation. So the vagina’s right here, here’s the condom [holding sieve above glass], just open this and here comes the ejaculation, right? [Pouring cream through sieve].
There is some sperm left in the condom, as you can see, but look here: The VAGINA IS FULL OF AIDS.
OK? This [gesturing at milk in glass] is all AIDS. There is still some AIDS left in the condom, but not a lot. But most of it is in the vagina. It’s a VAGINA FULL OF AIDS.
