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!

Puzzles! Brain Teasers! All in a little box! I try to keep things like this handy when traveling with the kids...or waiting for our order at a restaurant. Genius Decks

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

These Robot Lamps are great! It's very cool that they've designed a version in "girly" colors too. It's sad that so many girls don't get to have robot toys, just because they don't come in pink. Well, now they can!

Glass is an amazing substance. Even though it seems like a solid, glass is really a liquid! It's also very well suited for recycling. These beautiful bottle platters and fish tumblers
are made from recycled bottles. Cool beans!
These Pop Art Plates make me think "Abstract Art meets Biology". The colors are vibrant, and the patterns look wonderfully organic. Just beautiful!

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