Go to China ( place with the big gray wall being built ) and run to the right until you see a the gunpowder barrel on a platform .
on time tangled island [vikings]
Chances are that if you overload the charge in a revolver style black powder pistol, you can blow up the cylinder or blow the barrel off the end of the gun.
On Time Tangled Island, click on the crab several times until he explodes. (Not to worry, he rapidly pulls himself back together.)
If you click on him repeatedly, he will explode, then come back together.
The cave at 831 AD is covered by rocks. Get the barrel of gunpowder from the right side of the Great Wall of China in 1593 AD. Clicking on the rocks will automatically set off the gunpowder and open the cave. (see related question)
The one in the Viking Time It's a rocky place and easy to see
What game has a barrel to get into? The only one that really uses barrels are Time Tangled (gunpowder) and Nabooti (which has leaky barrels of explosives). (FYI : at the diamond mine, you can turn off the sparking switch so you don't blow yourself up.)
Take the barrel of explosives find the cannon postition the barrel under the tooth and hit it with the cannon!
you take the gunpowder {from china} and take it to the rocks and the flame will light it then BOOM! the cave will open...so good luck!
No
First you go to the Great Wall of China (1593 AD), all the way to the right is a barrel of gun powder, pick it up. Travel to the Viking Era (831 AD), climb up the cliffs, place the barrel of gunpowder in front of the rocks blocking the cave's entrance, the rocks will blow up and you can go in. GO down about one jump then cross over to the right. Climb up about 1-2 jumps then go fully around the outside. DO NOT go in the water. Grab the vase and go back to Ancient Greece (328 BC). Talk to the second warrior.
A Powder Keg will blow up on its own once the fuse runs out. In addition, using a weapon on it such as a bow or a bomb will cause it to blow up earlier.
