Since more and more Pentax bro/sis getting interested with strobist action, I guess I'll give the most basic way to overcome 1/180s limit.
The technique is flash frozen, nothing new. It's been around for a long long time. You basicly use the lowest ISO, narrow aperture (like f13-f22) and 3secs shutter. Then u MF and predict where the action u wanna frozen. Once that action takes place, u trigger the flash to capture that motion. Modern flash tends to be faster than 1/1000s and up to 1/10000s.
I'll use this person's setup as a guide.

Instead of cactus trigger, I'm using 2x SB-3000 slave mode and trigger with another weak flash manually (placed somewhere at the cactus position).
Here's what my quick setup gave me. I'd dropped ice into a shot glass. Background is a translucent light foam mat from Daiso. I'm using a blue color gel at the flash behind.
Have fun^^
