EXPLOSIVE Barrels!

Our next assignment in programming is to make a explosive barrel and a regular barrel. These barrels have to fit the layouts of our race tracks.

Here's a rough sketch of what I had in mind. 

Since my environment is more sci-fi/futuristic, I'de like my explosive barrel to contain hazardous plasma. When it explodes, it will spray blue fire in all directions. 

Here's a first-pass at the two barrel variants I made for UDK.

These models do not have their bump-maps yet and are still awaiting work in the material editor. The plasma will glow with a distorted, thick liquid texture that pans through the material.
