Reactions to do with dragon’s breath

Dragon’s breath is purple, so it leads me to believe that the ender dragon combusts potassium in its belly. Potassium is an alkali metal, and it reacts with water to make an explosion.

This should be implemented into Minecraft.

My idea is that if you manage to fill a cauldron with 8 bottles of dragon’s breath, you can obtain a bucket of dragon’s breath. When placed, a translucent purple fluid should be produced that attempts to spread out in its container. If there is no complete barrier within 8 blocks of the source of the gas, it should stop spreading. When you pour water onto it, an explosion as big as an uncharged creeper should occur (per block of dragon’s breath), with purple fire particles. The same should happen when a splash / lingering potion of water should be thrown at it. This would make an interesting defence, as well as a weapon.
