The Black Box of Sciency Doom!

What is in the black box of science? Tubes? Pipes? A purple gelatin monster? Of course the gelatin monster doesn’t work, but how about two tubes, that have openings at both end? My group and I have watched the tests and we came up with a theory. We built our theory around multiple points.

1) Mr. Smail poured water three different times in two different spots in the box;

2) The first pour came out immediately, and the water loss was minimal, which could be attributed to a slight bit of water getting caught;

3) The second pour didn't come out immediately, like it was caught on something;

4) The third pour, which appeared to be in the same spot as the second, came out, but there was significant water loss;

5) The third pour came out purple.

So my group and I  theorized that there were two spots to pour the water into. The first spot was a generic tube slanted down. Nothing obstructing or changing the water. The second spot was obstructed by some kind of filter. That is why the first pour didn't come out immediately. The filter needed the pressure before water could pass. Caught in the filter was a dye. So when the water was forced through the filter, it got dyed purple. That would also explain the water loss, since once pressure fell below the needed amount, water would stop.
