Endless chemicals and combinations can be used for pipe bombs. But you are right. I subscribe to American Fireworks News so I know you can buy enough well-made M80s to blow up the world if you want. It's all there for purchase if you bring your own car for transport. And they also sell chemicals that the labs have to list as being on the Homeland Security inventory.
If you are blowing glass or making ceramics there are still sources of depleted uranium. Legally, you can still buy up to 150 # year. This stuff is only 40% as radioactive as U238, but it would make the refuse from your wee bomb tick ominously.

Et al,
One of the original rocket fuels was an hypergolic mixture of Arozine-50 (50% monomethyl hydrazine and 50% dimethylunsymmetrical hydrazine (a known animal carcinogen). The oxidizer was Nitrogen Tetroxide (which got lost at Kennedy Space Center once and got me involved with NASA). Not that I didn't want to be an astronaught; every kid who was a civilian private pilot and flew helicopters for the Army did.
Goddard from Colorado used something similar.
The last Space Shuttles (STS - Surface to Space) used external tanks with liguid hydrogen and oxygen. Derned hypergolic. I invented a car once with these, but there were no motors that could withstand the blast force.
Don't know if that helps. A pipe bomb might have been something very different. Dynamite or even black powder? Various explosives? Unfortunately, these are all too readily available to the bad guys.

I'm so suspicious, I assumed on first reading that that was a cover story for trying to make a bomb.

What you have described is a typical pipe bomb and that is why is might have exploded. Many years ago when I was a fledgling un-eductaed aspiring chemist I was quite interested in rocket and fuel and the like. I remember one particular "test" where we
used a paper towel roll tube and fashioned a nozzle out of clay. Upon ignition the clay nozzle was blown out and the fuel proceeded to burn at an accelerated rate and completely consumed in just seconds. Yes we did have face shields but were quite distant
from the "Rocket Motor"!!!! What did I learn? Don't fool with this stuff. We then proceeded to spend $ on Estes rockets and then enjoyed the hobby!!!!
My surprise here is why did this team not realize that they were Making a "Bomb" in the first place and as reported that this group was sanctioned by the school- there was an obvious lack of "understanding of the principles" and "supervision"??????

No details on the mixture that was used.
The "rocket sounds like a galvanized pipe,...maybe threaded at both ends with screw on caps.
small hole in one of those caps for the ignition of the " rocket fuel".
If the fuel is "loose", or hole is too small or gets plugged, then the rocket becomes very dangerous.
Our Elementary School "Show and Tell" classes, we used only Commercial Model rocket engines, and the class was protected by thick LEXAN Blast shield.
Never attempt making your own rocket fuel,....trace contamination has been known to speed things up a little bit.

Does anyone have any further details on this? I am curious as to the formulation of the fuel. We have a project starting up in preparation for a 2018 competition that will require formulation testing.
