The explosives in the diamond mine are just to the left of the elevator. Turn off the elevator switch that's sparking, then push the explosives to the right. You turn the sparking switch back on to detonate it.
To use the explosives:
The only explosives are at the Diamond Mines. But you don't punch them: you use the switch (which makes sparks)to set off the barrel when it is in position.
There are barrels of explosives at the left side of the elevator. Click the sparking switch to turn it off, then slide a barrel across (first for the rock, then for the wall). When you turn the switch on again, it sets off the explosives.
In the Diamond Mine, the explosives to blast the rock wall are to the left of the elevator. Turn off the elevator switch (the sparking wire) and slide a barrel to the rock, then explode it by turning the switch back on. Repeat for the wall.
In the Diamond Mine, the explosives to blast the rock wall are to the left of the elevator. (There are as many as you need.) Turn off the elevator switch (the sparking wire) and slide a barrel to the rock, then explode it by turning the switch back on. Repeat for the wall.
Actually there are no explosives. Just when you get into the cave part you turn off the button. Then you go t the left of your screen and push the barrel to where you wan t it. Then turn the button back on and Boom! there you have it.
Inside the Diamond Mine on Nabooti Island, you must get through a rock wall. There are barrels of explosives to the left side of the elevator. To set them off, you use the shorted, sparking wire from the elevator control. Turn the elevator off, push a barrel across the floor, and then turn the elevator back on, igniting the trail of leaking explosives. You will need to blast twice : once for the rock in your way and once for the wall itself, at far right.
To blast away the rock and the wall at the far right, you can use the explosives next to the elevator in the diamond mine. Turn off the sparking switch, slide a barrel to the right, and then turn the switch back on, setting off the barrel. Once the rock is gone, repeat this for the wall, and you can enter the mine cart ride.
In the Diamond Mine, blast the wall (and the rock that is in your way) using the explosives stored behind the elevator. Turn off the sparking elevator switch, and slide the barrel to the right. Turn the switch back on to set it off. Use one barrel for the rock and one for the wall. You get as many as you need.
Slide them to the right from the left side of the elevator. In the Diamond Mine, the explosives to blast the rock wall are to the left of the elevator. Turn off the elevator switch (the sparking wire) and slide a barrel to the rock, then explode it by turning the switch back on. Repeat for the wall.
Slide them from the left of the elevator. Be sure to turn off the sparking switch before you do, because that's how you set them off.
Turn off the sparking switch by pressing it. Then push a barrel over to the rock and turn the switch back on. This will set off the explosive and clear the rock. Then turn off the switch again and push another barrel over so you can blast the rock wall.
In the Diamond Mine, there are explosives behind the elevator to your left. To blast the wall, you have to turn off the sparking switch, then slide a barrel right to the big rock, then turn the switch back on to set it off. Repeat with a second barrel for the wall at the far right, which leads to the mine cart challenge.
