How do you get the second gem in area 51 of crash bandicoot warped?

1.try slide jumping too get it

2.go to a level where it has a timer,stand on a blue gem, it will take you to space! try going back to snow go,complete the obstical,fall in a hole (you will not lose a life)you get a red gem

;)

note:if all this does not work theres another one of these questions.
