Do they actually go to the moon? Outer space? Where do they end up?

answers:
Averager say: They will pop and falls back to the ground
-
Quadrillian say: They usually drop down or bob up again depending on their support in my experience.
Cheers!

elmechino say: Back on the ground or in the water somewhere, creating litter in places where there should be none.

spot a say: Upwards with the wind. The helium leaks out through tiny holes and they come down, or if they are rubber they might rise until they expand and pop, probably at a height a lot lower than everest

timespiral say: This is routinely done twice a day at 00z/12z (UTC) at many weather stations (usually government run) across the planet. They typically use hydrogen gas. The data collected is weather model food which is churned through massive physics equations in super computers and the output results in your weather forecast (or one of the outputs that a meteorologist will interpret to make a forecast). These types of balloons typically go up about 100,000 feet past the tropopause and into the stratosphere. The equatorial locations have greater scale height than polar regions which affects terminal elevation. Most of the balloons burst. They expand from room size to the size of a house at the lowest pressures. However, sometimes they do not burst. These types are classified as floating balloons and they may remain for many hours at peak elevation before bursting. The trajectory of the balloon is dependent on the upper level winds. There can be wide variation on the ultimate path taken. In summertime, in low latitude locations the range of the balloon might not be that great at all. And may land/crash not far from launch site. In wintertime, the jet stream is usually most active and balloons can be carried 100s of miles away. There are many different types of users/communities of this data. To name a few; aviation, agricultural, marine, general public safety,
