Big value and even bigger fun! The Tandem-X Launch Set includes the impressive, easy-to-assemble Amazon rocket (over 29 in. tall!) and the high-performance Crossfire ISX rocket. The Amazon builds quick with pre-colored plastic parts and self-stick graphics. The Crossfire ISX is a perfect next-step to an Intermediate level model with laser cut wood fins and self-stick decals.

LAUNCH SYSTEM INCLUDED.

Estes engine bulk packs are convenient and include everything your students need to prepare their rockets for launching.

Officially it’s the LAMPMU – Low Altitude Mars Personal Maneuvering Unit – but no one ever calls it that. To most people, on Earth and on Mars, it’s simply “The Leaper™.” Developed for the first Mars Expedition of 2035, the jetpack was envisioned as a way to rapidly travel between surface habitats. What the engineers didn’t count on was just how fun it would be! Why walk when you can leap!
