Explosion/Message Script (very basic)

It's in the title

while true do
wait(60)
local m = Instance.new("Message")
local e = Instance.new("Explosion")
e.Parent = game.Workspace
m.Parent = game.Workspace
m.Text = "PREPARE TO DIE!!! MWUHAHAHAA!!!!!" --change the message text here!
wait(3)
m:remove()
e.BlastPressure = 100 --change this number to how strong you want it to be
e.BlastRaduis = 5000 --change this to the amount of distance it goes!
end
