Ants... In... Space
Ant writes "The Fowler students picked an experiment with ants, rather than plants, because they wanted to see some activity in space. They have been following the ants' progress on the web. The students and their teachers also have learned that sometimes the best thought-out hypothesis does not pan out in reality. 'We predicted that the ants would tunnel a lot slower in microgravity, but we're finding out they're moving a lot faster,' said Golash. The students have a control group of ants at their school, living in a similar environment except with gravity. After the shuttle returns from its scheduled 16-day flight in early February, the young scientists will have 30 days to put together a preliminary report. Their "Ants in Space" experiment was sponsored by SPACEHAB, an aerospace company that has worked with NASA for many years to design and build hardware for space experiments."
Launch Preparations: $130 million
Anti-Grav Ant Colony: $2000
The fact that 30 years after we put man on the moon, this is the best NASA can come up with: Unfathomible.
You know, how about we try seeing how ants tunnel in Lunar Regolith, or Martian soil. That would be intersting.
This is great for the kids, but I think it just shows how far NASA has NOT come.

I could only attribute this to concepts based on hinderences to human's movements in space. They probably assumed that since Humans have a harder time coordinating while in space suits on different worlds that Ants would have a harder time coordinating in small tunnels in a controled environment.
This of course has so far been proved false, because the Ants have several legs and movement through said tunnels would probably be easier with lower gravity in the same way humans could probably move faster in tunnels on the moon than we could here on earth. Think of it this way, we could jump down a cooridor on the moon far faster than we could walk run or crawl through it on earth.
It wasn't until Buzz Aldrin's EVA during the last Gemini mission that they had worked out a set of maneuvers and restraints to make sure that when an astronaut turned a knob, he didn't turn instead.
Now, an ant is never free floating. She always has something to hold onto, the tunnel. But if we have learned anything in space, you really can't assume anything. You have to observe it and see how it actually behaves.
Take fire for instance. You take it for granted here on earth that you can see the flames. Well, flames are caused by convection, which does't happen in micro-gravity. Hot air has the same "weight" as cold air. Instead the plasma forms a sphere that is tricky to see. Smoke does not rise from the fire for the very same reason.
With that sort of information, NASA found they had to design completely new fire detection systems for the ISS.

2. We probably wasted thousands of tax dollars on this experiment.
You're nothing; like me.
Another thing you need to remember that hasn't been pointed out yet is that while the forces do indeed propogate upwards, they disperse. They don't maintain their strength in the way I'm almost certain you're imagining, they get weaker and weaker, until quite rapidly they are simply swamped by simple friction and other electromagnetic effects and get absorbed into the system as incredibly tiny amounts of heat.
This is why when you jump on the ground, nobody on the opposite side of the planet suddenly feels a bump. The forces disperse to effective nonexistance (since they can't be conceivably detected anymore). Even really really large bumbs like Richter 7.5 earthquakes require very sensitive devices to detect them after a few hundred miles.
