A Real Miniature Car, Powered by Hydrogen Fuel!
This is pretty cool! With this meter, you can monitor how much power your appliances use. This would be great for doing an experiment testing different lightbulbs, comparing a regular applience with an "energy star" version, and more.
Kill A Wat Electricity Usage Monitor - connect appliances to the Kill A Wattâ„¢, and it will assess how efficient they really are.

Useful Mathematical and Physical Formulae is a handy little book, with quirky and fun illustrations. The author, Matthew Watkins, was kind enough to donate a signed copy to Art Intersect Science a couple years ago.
This is a great starting telescope, and has a very comfortable-round shape. Astroscan Telescope is a high-performance telescope that is easy-to-use, maintenance-free and completely portable.
A long time ago, there was a great store in Noe Valley called "Star Magic". It had all kinds of cool stuff in it, most of it to do with space and science (but not all). That's where I bought an Astroscan telescope as a gift for my husband and eventually discovered Edmund Scientifics. Years later, GalaxyGoo became an Edmund Scientifics affiliate, and we're now linking to one of their products: the Astroscan telescope. Funny how life travels these little circles and spirals.
Up for a little time travel? Let's way go back to days of morse-code and the early "wireless". I haven't tried these kits yet, but they look very interesting: Radio Receiver and Morse Code Kit
The product description says that they're best for ages 10 and up. However, they also say, with adult supervision, they're good for ages 3 and up. Cool! Sounds like a family activity to me!

Shape Scapes Sculpture Set pieces have curvey shapes. Not your average construction set. While supposedly a kid's toy, it's also a nice desk toy.

The Color Splash Camera looks like a lot of fun. Retro and techy, at the same time.

Cool little stocking-stuffer: Staple-Less Stapler

This jewelry is based on molecular forms: DNA, Serotonin, and Dopamine

In college, I lived in Albuquerque, New Mexico. While there, I learned to appreciate a fine hot sauce...and the difference between red and green chili. I also learned that I prefer flavor intensity over hotness. That's probably why this Build your own Hot Sauce kit caught my attention.
Hand Boilers are looped and twisted glass sculptures containing a colored liquid that will "boil" as heat is transferred from your bare hand. Very cool!

Nebula Plasma Ball - Creates an amazing light show - and responds to touch on the glass sphere.

This design is based on our click-n-spell with the elements game. Chocolate is spelled out with symbols from the periodic table of elements.

Lego Mindstorms! This is at the very top of my 7-year-old's wish list. To be honest, I can't wait to play with it too!
I love Peet's coffee, and I just had to order a sampler...to test out the affiliate system. I'm loving the coffee! There's a Peet's over the hill from me, so paying for shipping is wasteful. But I still want to benefit GalaxyGoo. Happily, Peet's has a Card program, so I can just buy a reloadable card and benefit GalaxyGoo with my local purchase.
Are you lucky enough to have a Peet's nearby? Order, or reload, your own Peet's card through our affiliate link:
I love my lava lamp! I can't imagine my office without it. This updated version has a metallic sheen to them, with the original hypnotic-organic-blobby movement.
Ahhh, Peet's coffee. yum!
Many say that Peet's is the best coffee in San Francisco, and now you can get some for yourself and support the educational projects at GalaxyGoo at the same time. GalaxyGoo has been approved as an affiliate of Peet's :-)
They have fair trade blends, so you have even more to feel good about while you caffinate.
Granted, these aren't exactly related to science, in any way...but they're so darn cute and geeky!
