Ok so this summer my 7 and 13 year old got to try out some things so I can vouch for these things as high on the "OH WOW!" scale:
a sea viewer, a squid/fish attracting light (we really did get squid and some of the biggest flying fish
I have seen, not to mention a host of critters I couldn't identify,) and a good little net to catch the critters. And a good waterproof monocular. Oh and the stove
for baking (cookies especially) was a big hit. So how about you all?
