Chemistry

It might just be a local stable energy configuration and it could potentially be easily tipped over to a much more stable energy position. Therefore, even though it's a triple bond, it could still be extremely reactive.

While not exactly fitting the situation you can take for example H2 gas and O2 gas being combined and with a little bit of heat energy they can spontaneously form H2O and release a lot of energy in the form of an explosion. Both gases are very stable but H2O is far more stable.
