Explorers/Headscratchers


 * The Applied Phlebotinum of the film is a circuit capable to generate a force field which can be translated and rotated with a computer. On the other hand, the so-called "Thunderroad" was a hunk of junk that did not provide any function whatsoever. So why did the kids need to steal the Thunderroad before going to space? They could've just sat inside the forcefield with the computer and the battery, and they would've experienced a much more spectacular 360° view.
 * They're kids, making cool things without necessarily thinking about the practical aspects is what they do.
 * Also, they wanted something to actually sit on, and something to hook their oxygen tanks to (before they got an upgrade for the chip that would also give them oxygen).
 * The other kids are justly impressed when Wolfgang shows them that the force field has so far been powered by a small 9V battery. What was powering the computer and its CRT display then? The Apple IIc was supposed to be portable, but that was with a smaller, flat screen and a big external battery pack.
