Time Bomb. (Trap Idea)

[Me163]

This is an idea for a new trap called the Time Bomb.
It would look like a storage barrel of TNT (like what max wallbreakers carry) but with a big analog clock taped to it.

The Time Bomb does a little more damage than a giant bomb but takes 1-2, maybe even 3 seconds to explode. A useful purpose for it would be to plant next to your town hall when you're leaving it outside your base and also to have a better defense against balloons and golems since they move very slow. If a balloon is blown up by a time bomb, the balloon does not cause any damage to your base defense.

It would only explode if a troop or a serial of troops stay in its blast radius for the whole 1-3 seconds. There would be a ticking clock sound when the troops hang out in the blast radius.
