I’m not entirely sure what you mean. The most energetic explosion that humans can currently create on Earth is probably from a fusion bomb, which works by merging light elements into heavier ones to release huge amounts of energy in the process.
There is a really fun explosion that you can make yourself. Ask your parents to help you set this up outside so that you don’t get in trouble for making mess!
Take a big bottle of of diet coke and stand it up with the lid off. Take a 3 or 4 Mentos (the minty sweets) and carefully drop them into the bottle. Stand back!
The mentos react with the coke and cause a fizzy explosion.
You can look it up on youtube too.
