Crystal Growing

Company’s Description - With this revolutionary approach to teaching chemistry, you can make your own happy atoms! This physical and digital system lets you discover the world of molecules in an intuitive, hands-on way. Using a set of 17 atom models representing 6 different elements, you can assemble your own molecular models. The atoms connect easily with magnets: metal tips on the ends of rubbery arms, which represent free electrons, snap onto magnetic bonding sites on the atom spheres, which represent empty spots for electrons in the atom’s outermost electron shell.

With the Happy Atoms Introductory Set, you can snap together hundreds of different molecules. Because the atoms already have the correct number of free electrons and empty bonding sites, it is difficult to build a molecule that doesn't actually exist. Happy Atoms function like the building blocks of the universe!

Happy Atoms Intro Set

17 atoms. **Does not include the Quickstart guide or periodic table but can still be used along with the downloadable app.

With the Happy Atoms Complete Set, you can snap together thousands of different molecules. Because the atoms already have the correct number of free electrons and empty bonding sites, it is difficult to build a molecule that doesn't actually exist. Happy Atoms function like the building blocks of the universe! The digital component takes this molecular modeling system to the next level. Using the Happy Atoms app and the camera on your tablet or smartphone running iOS or Android, you can scan molecules you build. The app then uses state-of-the-art image recognition technology to identify the molecules.

Happy Atoms Complete Set (50 Atoms)

New, in box. Seal broken. Contents untouched: Explore hydraulics, pneumatics, and robotics with your very own GIANT hydraulic hand! Using over 200 plastic pieces and piston tubes that you fill with water, build an awesome mechanical hand that uses hydraulic power to simulate the movements of the human hand no motors or electricity required! Once assembled, your cyborg hand slips onto your own hand like a glove, with mechanical fingers that you operate with your own fingers and that can grip objects with enough force to lift them. Challenge yourself to pick up and hold a variety of items. The hand can be configured in three ways left hand, right hand, and claw-like, with the thumb in the center and can be adjusted to fit virtually all hand sizes. A 40-page, full-color manual guides model building and experimentation and provides engaging scientific information about how pneumatic and hydraulic systems are used in industrial robots to assist with a variety of tasks in our world
