Any ideas for this creation I made like what I should make with it?

You should make it onTouch and THEN make it red... then maybe make them smaller, and invisible. You could make them come visible again when you touch it.

debounce = false
local function onTouch(Object)
	local mine = script.Parent -- assuming you inserted the script in the mine
	if (debounce ~= false) then return end

	debounce = true		
	local char = Object.Parent:FindFirstChild("Humanoid")
		if (char ~= nil) then
			local play = game.Players:GetPlayerFromCharacter(Object.Parent)
			if (play ~= nil) then
				
				mine.Transparency = 0
				mine.BrickColor = BrickColor.new("Really red")
				wait(1)
				-- insert explode script you have in your mines already
				
			end	
		end
		debounce = false
end

script.Parent.Touched:connect(onTouch)

Good job! Good luck!
