OK, I'm only gonna post about my solar balloons when something big happens. Y'all probably read my other posts. I had to get on here and say that one of my 5-foot tall solar tetrahedron-shaped hot air balloons went approximately 170 miles in about 5 hrs. Two were released that day, one around 11.30 am and one at about 1-something pm. I got a return that same day from the second one, it had gone about 40 miles. (I posted about that one.) Just yesterday someone found the other one and sent me the email today. I am amazed at the distance accomplished in only 5 hours.
