Hi, Sandra
some pills are not supposed to be crushed or even split due to an enteric coating - some NSAIDs (like my RA med, Lodine) is like this. Check the label or ask the pharmacist. These would be a good candidate for the slippery coating trick.

For the pills that can be crushed, you can get an actual pill crusher to make it easier.

Best of luck and congrat's on going tubeless!
