my friend said people could build powerful bombs out of stuff you can buy at walmart. i laughed. thats just false right?

It is false. There are certain types of materials that, when combined, have the potential to create an explosive device. However, these substances are rarely found in everyday items and it is not possible to build a powerful bomb by merely purchasing items from a retail store such as Walmart.
