When the mixture is sealed properly, the pressure builds just enough to give that satisfying burst. It’s a simple way to explore chemistry while making something fun. Safety note: Stick to safe materials only. Don’t attempt real explosive crackers or anything involving fire. Always use eye protection and keep it educational. Like this DIY? Follow @teachyouman
