@RobertM: In 1973 my HS chemistry teacher convinced several of us to book on a cruise out to Africa...
You got to meet (well, see) Neil Armstrong and Isaac Isaac Asimov -- AND a full eclipse for 8 minutes of totality? Best high school chemistry teacher ever!!! I hope you thanked him or her for persuading you to have this amazing life experience!
@amacon: We handed out the solar eyeglasses to everyone at Christmas including books for the kids explaining eclipses...
It's great that you are doing this as a family -- something for everyone to remember -- you say you live in the southern US -- have you thought about making a trip/holiday of it to see the total eclipse?
We handed out the solar eyeglasses to everyone at Christmas including books for the kids explaining eclipses - we live in the southern US and the kids actually checked out cloud coverage for the entire US to verify we would have good opportunities for viewing.
In 1973 my HS chemistry teacher convinced several of us to book on a cruise out to Africa, nere the Canary Is., where the ship tracked the eclipse for 8 minutes of totality. Lots of science notables were on board - Neil Armstraing, Isaac Azimov - and the ship deck was covered with tripods and astronomy buffs just prior to totality. At the moment of the total eclipse, a deafening sound of shutters erupted, followed very shortly after with laughter from the sound, and then collective "ooohs" and "ahhs" from those present. I even found a link to the event: https://en.wikipedia.org/wiki/Solar_eclipse_of_June_30,_1973#Observations
@Elizabeth - "I remember the last partial eclipse I saw that the shadows looked strange..."
I think this is because, as Betajet points out above, a leafy tree has the effect of many pinholes, so the sun shining through them will appear as crescent-shaped blobs of light instead of round ones. Also I think light diffusion through the non-eclipsed part of the atmosphere gives a different effect from the sun being below the horizon.
Oh, and put something over your video camera lens if you don't want to burn out the sensor (sooty glass / ND filters / a lens from a pair of eclipse sunglasses....)
In the good old days :-) we used to take a piece of glass and hold it over a candle flame so it got covered in soot. When it was black enough that you couldn't (or could hardly) see a normal scene through it, it was dark enough.
For photography you can use ND (Neutral Density) filters - but use a lot of them, they go up to ND8 usually (let 1/8 of the light through) and I'd probably want to use 3 of them at least. You don't see them around as much now with digital cameras as in the old film days. And point your camera at the sun for the minimum possible time. (or you could just sacrifice a UV filter and use the soot trick above :-)
