30 Things in Your House That Could Explode

21. Espresso machines

The words, “Do not remove filter unit when under pressure,” are good advice. You know this if you’ve ever had to clean up the aftermath of a coffee bomb.

22. Boiling salted water

The scientific jury is still out on this one, but I personally witnessed a panful of salty water explode upward and outward about 2 feet, with very serious results. Current theory points to overly salinated softened water as the cause.

23. Ice cubes dropped in hot liquid

Exploding ice can actually break the glass or mug.

24. Hot/cold glass filled with cold/hot liquid

Seems like you can do this a hundred times with no problem, but sometimes the glass shatters, even violently.

25. Firewood

The familiar popping of a real wood-burning fireplace is actually little explosions of trapped pitch, sap or water. Cozy, no?

26. TV tube

An old fashioned TV tube is much harder to break than a light bulb, but it implodes just like one. A very good reason not to buy a real tool set for your two-year-old.

27. Batteries

Many household batteries are theoretically explosive, while car battery explosions are by far the most common.

28. Septic tank

Problems with a system can lead to methane buildup. Not the best place for plumbers to take a smoke break.

29. Trees

Trees can explode due to fire or a lightning strike, both of which heat the water in the wood. Extreme cold can freeze the sap inside maple trees, causing it to expand.

30. Mentos and Diet Coke

If you haven’t tried this awesome kid experiment, suffice it to say that you should never wash down 11 Mentos candies with a half-liter of Diet Coke.

Thank you for the list. I had never heard of mentos and diet coke?

One good tip is in storing old used batteries (B,C,D) is to put a piece of black tape across the ends, if stored in a container that can be bumped or in a bag, they eventually build up heat if ends are touching each other, and they will smoke and eventually end up with a fire. Someone almost lost their whole house, when storing these batteries in a bag in the garage. Do not wait until you have a lot of them if you do not use that thicker black tape. (for electrical?) They are not supposed to be put in the garbage. There are places where you can take them.

I knew most of these and have even experienced a few. Didn't know about exploding pumpkins, though. Sounds like a music group. Oh wait .... that's Smashing Pumpkins:, I think I like Exploding Pumpkins better.
