Is your campfire trying to kill you? Exploding Rocks & Concrete

The video explores the potential dangers of exploding concrete and rocks when exposed to high heat. It begins with an introduction to the phenomenon and proceeds with experiments using different concrete mixes, including those with Orbeez, rebar, and steel BBS. The video also tests the explosion potential of various rocks in a campfire, both wet and dry. The results show that while small explosions occur, they are not significantly dangerous. The video concludes with a DIY super spalling concrete mix test, demonstrating the explosive potential when molten aluminum is poured into it.
