Step up solution

Hi - I have a 24 v air pump, that I'd like to mount on a chassis - the idea being I can use it to fire nerf pellets !
What I'm looking for is a simple (cheap ) cvoltage step up solution - the chassis I'd like to mount it on uses a 9 V alarm battery - has anyone got a good compact IC for instance that woudl do the job ??
I'm not too worried about the battery flattening as it'll only be required to supply a "puff" - but need the 24V to ensure that it's a good strong one.
Any suggestions ???

HI Kwinn -- can you suggest any particular product ???

What I meant was that you use a 555 timer chip and a voltage tripler circuit to charge a large capacitor that provides power for your "puff" of air. See http://en.wikipedia.org/wiki/Voltage_multiplier for an explanation of the basic circuit. Of course you would have to add a capacitor large enough to power the circuit that provides the puff.
I'm a fan of LiPos but you'd also need a charger to go with the batteries.
I've purchased many LiPos from HobbyKing. I use their 5Ah 3-cells to power our Nerf Vulcan foam dart gun.
BTW a 3-cell 5Ah LiPo weight 405g, so a 6-cell (which would be close to 24V) would weigh 810g. I bet that's a lot less than a SLA weighs.
LiPo batteries have such a good power to weight ratio, anyone interested in robotics ought to seriously consider getting some LiPos and a charger. They're not nearly as expensive as they were a few years ago.
