How can you make explosives snowballs in 1.15.1 java edition? [duplicate]

For a map my friend was making, I was trying to make grenades but they failed. I need a data tag that can make it so that as soon as it touches the ground it explodes.

You need something like this:

execute as @e[type=minecraft:snowball] at @s anchored eyes unless block ^ ^ ^1 air run summon tnt

obviously, this will not work for all angles but there's the template. If you don't want it to destroy blocks, summon a creeper instead:

execute as @e[type=minecraft:snowball] at @s anchored eyes unless block ^ ^ ^1 air run summon creeper ~ ~ ~ {Fuse:0,ExplosionRadius:1}

and disable mob griefing /gamerule mobGriefing false
