Compress them hard enough and fast enough, and you'll generate enough heat to make them ignite.

Why do they have to be ignited? Let's just call it a Moral Imperative, and leave it at that.

Well the use of unignited ones is just not advisable.
Especially after what happened LAST TIME.

Last time?! Good grief, no one wants that to happen again. The cleanup alone took days and I still get all queasy at the sight of the color blue.

I had no idea those little white Smurf hats would fit hamsters so well.

Well why did you think they make them in size H?

Because they're little pains in the ass? H for Hemorrhoids?

It turns out that Hamsters produce large amounts of Helium-3.

More like 14C-methane!

So long as you don't use lithium-7 as a tamper.

maybe what you're doing won't get them to ignition temperature,but with sufficient resources to control the application of energy you could just do that alongside whatever you needed them to be that hot for. weather that's useful to do, is another story ;)
edit: pretty sure I missed the point but that's just what popped into my head XD

Welding techniques using structure bearing hamsters was never a good idea to begin with.

Of course you'd say that. Now I'm imagining a building made of hamsters lol.

I totally understand. I have broken the sound barrier once, but you must never ask me how...

These will be some really fun commissions to see!

Look closely into Iron Man's chest Arc Reactor, you'll get your answer

Well, if they Don't reach Crucial Ignition Temperature then they'll not ignite the Flux Capacter, and we'll be Stuck here Another Twenty years!

LOL!! I Love the Concept, Great idea!!

Your just grumpy because someone stole your mint i bet *discreetly chews on one* XD !! ^v^

I am a little amused. What could be a WTH/WTF moment with a Unicorn?

are you going for a shotgun version of the fire pig attack the Romans used

Are you pondering what I'm pondering?

I think so, Brain, but will Snowball fit in a Dolly Madison package? NARF!

Perhaps mouse fusion would work better.

Jeb thought the hamsters would make good rocket fuel for a Mun shot.

The solution is quite simple, my dear roo, just use ferrets instead. They're basically Internal Combustion Engines with fur anyway, and they run on sugar. Just don't make the same mistake I did and give then Element Zero. Damn thing exploded and imploded at the same time, and the ME field it left behind made the whole place go to plaid. PLAID! We were stuck at Ridiculous Speed until we could get the peanut butter off the cactus, and even then we all had fuzzy dice hanging off our noses for weeks.

Smash cut to: Kaiju scale hamsters, rampaging across the countryside, while Flinters tries to flee their wrath.
