This air rocket used a different kind of compressed air system that uses a weak bicycle pump that This air rocket used a different kind of compressed air system that uses a weak bicycle pump that utilizes a button release valve system. If you don’t do it quick it gets weaker. Finding the altitude utilizes a button release valve system. If you don’t do it quick it gets weaker. Finding the altitude of this rocket was difficult mainly because the Altimeter was too heavy for the light plastic rocket of this rocket was difficult mainly because the Altimeter was too heavy for the light plastic rocket and the propulsion system wasn't enough to propel it high enough. The results show that this and the propulsion system wasn't enough to propel it high enough. The results show that this type of propulsion system is inferior to the high pressure air release system used by the tridium type of propulsion system is inferior to the high pressure air release system used by the tridium air rocket and the solid fuel rocket but is still a effective rocket.air rocket and the solid fuel rocket but is still a effective rocket.

DiscussionDiscussion

The results show that the Max Trax was superior The results show that the Max Trax was superior in speed but not unmatched in altitude.in speed but not unmatched in altitude.
