Build a real head of live steam in the boiler, ease the throttle open and watch the engine take off. The stationary steam plants have nickel plated brass horizontal boiler, water gauge, whistle, safety valve, throttle, 3" dia flywheel and power takeoff pulley. Our dry pellet fuel model (includes 20 fuel pellets) has a single action horizontal piston engine and comes as a kit. It requires about 2 hours to assemble and mount on its roughly 7" sq base, using simple tools like pliers and screwdriver. Assembly adds to the fun and cuts the price! All parts of each are precision metal, plated or enameled as appropriate. Select a small DC motor that will operate as a generator from our catalogs and see if you can become a 19th century electric utility!! Requires light assembly. Ages 10 and up. Add a box of (20) extra fuel pellets for even more hours of enjoyment!

Impressive, this 3-foot Lizard King. The 1:14 scale plastic model of a Tyrannosaurus Rex skeleton has 51 bones that snap together, then snap apart easily for later use, which is more than you can say about the original. Measures 36" long, and comes with a display stand. Bones are nicely aged for paleontological verisimilitude. Very nice kit, with legs, as they say! For ages 8 and up.

Miniature Masonry Snap-together building blocks? Those are for cowards. We spit on those. Tough kids use Mini Bricks, monument kits that come with teensy faux-stone textured plastic blocks (1/4” cubes or 1/4” x 1/4” x 1/2", among others), mortar, a mixing tub and a very, very small trowel. You pick the Coliseum (approx 5” dia) or the Statue of Liberty, both with 132 pieces, instructions, and mounting bases. (You don’t build Lady Liberty. She’s in faux-copper, 3” tall; you build the base.) Suitable for kids with small-motor skills and patience. Neatness counts.

Cleverly made, and mighty heuristic, too. You pick from a variety of Pathfinders hydraulic-system teaching kits made up of unfinished wood, transparent tubing, and plastic syringes, which power the movement. The finished mini excavator will stand approx 10” tall on a 7-1/8” x 3-1/4” base, with a 5” x 2-1/4” claw, and (4) syringes. The mini scissors lift has a 9-1/2” x 3-1/2” base and a 3-3/8” x 7” platform and a single syringe. For someone entranced by hydraulics, or for a whole classroom of students, there’s the 4-In-1 kit, with the excavator and scissors lift, plus a cherry picker and platform lifter. Very clever teaching tools for ages 8 and up.
