LATEX WEATHER BALLOON 8 FOOT DIAMETER
Giant Weather Balloon
If the question is whether to tie a bunch of these giant latex professional weather balloons to a lawn chair, the answer is no. (They burst at about 82,000 feet anyway.) Besides, this is a true weather balloon, with plenty of fun, nonfatal uses. The cream-colored latex balloon is approx 40" dia when flaccid, you should pardon the expression, but has an 8-foot dia when inflated. The neck is 9" long x 1" dia. Scientists, meteorologists, inventors, teachers and the imaginative filmmaker are warned to launch the balloon carefully. The material is delicate and not made to survive brushes with pavement, pine branches, or clumsy physics students.

US MAP PLACEMAT
EAT SMART
They might as well learn something while they're trying to outlast you on eating those lima beans. Set the table with educational placemats and they'll be at least a touch smarter after dinner, even if their vegetable intake is low. These laminated, 12" x 17-3/8" mats have full-color fronts, black-and-white backs. Choose the United States Map, Stars & Constellations, the Periodic Table of Elements or The Metric System.

8 FOOT SOLAR BALLOON
It Can Fly!
Blow up this big, 8-foot long x 2-foot dia, solar balloon on a sunny day and then sit there, maybe enjoying a refreshing beverage, and watch while the sun heats up the black surface and the air inside expands and becomes lighter than the surrounding atmosphere and the whole thing rises like your hopes for a bright future. Includes a 20-foot cord to keep it in check. Works best on a cool but bright day. Don't we all.

GIANT WEATHER BALLOON
Reaching The End Of Your Tether?
That would be approx 600 feet, if your tether is attached to this latex floater, aka “meteorological balloon for tethered flight.” These are heavier than most weather balloons, which make them perfect for parties and events. Max height is 500-600 feet. Made for filling with helium/hydrogen, and will burst at approx 8-feet dia. Our current stock is red, but don't hate us if you get a white, green or orange. Make a statement with it.

MAGNETIC POLE FINDER
Alnico On A Gimbal
Sounds like a Portuguese percussion album, but it’s just an alnico bar magnet in a mount that lets it rotate freely to demonstrate the three-dimensional magnetic field. Ideal for experiments about forces between magnetic poles, fields around wire and coils, and the properties of fields produced by electric currents. Also handy as part of your ghost-hunting gear.

4" ANTIQUE-STYLE GLOBE
Knowledge Is Globular
Put the world on a desktop with these 4" dia swivel-and-tilt globes. You pick from: the topographic globe with country borders and names or the antique-style political globe that shows current countries but in earth tones without topographic details. Both have vertical and horizontal axes and stand on a 3-inch base. Made in Germany.
