Jet's Time Machine is the second half of the thirty-fifth episode of Ready Jet Go!.
Jet uses his Bortronian skills to test his first experimental Time Machine so he and his Earthie friends can go back to an exact time - 3 minutes earlier - in order to see a spectacular moment in a meteor shower that they missed. A mistake happens the first time, so he keeps trying to go back in time to fix the first mistake, but more mistakes keep happening and snowball into hilarity.
- It is revealed that time travel is possible in the Ready Jet Go! universe.
- After Jet and the gang finally get to see the meteor shower, they are never shown going back to the present, which might mean that they are stuck in an alternate timeline, since Jet dismantled the time machine so the kids couldn't tamper with time anymore.
- This episode takes place entirely at night.
- Purposes for which the kids wanted to time travel:
- Sean - to meet Neil Armstrong.
- Sydney - to go to the future.
- Mindy - to go back in time and find the hat she made for Stuffy Bear.
- Jet - to go back in time and ask for seconds of a delicious pie.
