fun explosions with chemistry at home explosions/ reactions created at home involving things of daily use - eg - phenol, mouthwash,soda,  coca cola, salt etc.  anything involving common objects (found at home) will do, as long as they are not too dangerous or serious explosives.  for example --  mentos dropped in coca cola gives us an explosion and lots of effervescence.  we need it for chemistry lab experiments, and will be practising under adult supervision.   please reply quickly :)

First and foremost, the previous posters are totally correct about safety as a potential issue here. Second, effervescence and explosions are two quite different things. It sounds like what you are actually looking for are reactions that produce a fairly large amount of gas quickly. There are a number of common household ways to do this, some safer than others. In order to be safe, you should always work in a shatterproof container with a wide opening. NEVER use a closed or narrow necked container; gases can build up large pressure quickly, and even a plastic container can become a dangerous device. Also, be prepared for a mess. When I do soda and Mentos "fountains" with a class, we do it outdoors and then hose down the area.

Here are some things that you can try, following the safety precautions above:

Baking soda + any acid (vinegar, lemon juice, soda)  - this can be made more effervescent by adding a squirt of dishwashing soap to the acid before mixing with the baking soda

Alka Seltzer tablets are fun; if you add soap to the water before you drop the tablets in, you get a lot more foam.

You can make your own fizzy "bath bombs" by mixing baking soda and citric acid granules with scented oil; see the instructions here.

There's a really neat variation on the baking soda and vinegar routine here. It's more work, but unique.

And, here is a link to instructions to make a chemical reaction that creates a "lava lamp" effect in a bottle. Easy and fun.

Have fun, and BE SAFE!

I agree with post #2 completely.  You never want to underestimate the power of chemicals or chemistry in general.  Some of the most common household ingredients could result in really dangerous combinations. I would not want to be liable in this situation if you accidentally blew yourself up.

I don't think it's a good to play with explosions at home. Even experiments that seem safe can be actually dangerous. You need not only adult supervision, but also safety equipment. It's not as simple as just putting Mentos in a Coke bottle and standing back.
