Does anyone know how to use this micro capillary tube and dispenser?

I got a home TLC kit and everything is pretty self explanatory except for the use of this one tool.

The video just shows the guy pushing the micro capillary tube into the little rubber bushing and it stays in place.

Mine just falls out. There is no hole in the little rubber bushing and it seems to me that there should be.

Do I poke a hole in it? Do I force the capillary tube through the rubber and end up the the tube embedded in my finger? LOL

Just not sure how this is supposed to work.

Thanks

Never mind. It was the obvious. I poked a hole and it's working great.
