Any tips on how i can make my ears pop?

Hold your nose and blow real hard while traveling to space.

This is usually caused by the Eustachian tubes - the passages that connect your inner ear and the back of your throat - being obstructed for some reason, so the pressure on the outside of your eardrum is not the same as that on the inside.

One thing you could try is tipping your head back, yawning widely and working your jaw from side to side. Sometimes that opens the tubes enough for the pressure to equalise.

If that doesn't work, try the method I've used since childhood: pinch your nose shut, close your mouth tightly and blow gently. My recollection is that the medical consensus is that this isn't a great way to do it, since there's the potential for the pressure in your throat to push bacterial crud from your throat up the Eustachian tubes, and that can result in an infection. FWIW, I've never had that problem.
