Last week we all wondered just what that strange black thing as in the skies of Somerville New Jersey. Well, it seems like we might have an answer...
A kind reader sent up a link the other day in regards to a story we had covered on a strange ighting in the skies over New Jersey and it leads us to this interesting thing:
It is an advertisement for a 60 foot black tube (very much like the one seen floating in the skies above New Jersey) used for performing certain science projects. Here is what the website says:
Solar Tube Balloon
60 Ft Solar Energy Experiment
By Educational Innovations
Watch as this giant solar tube gently lifts into the air. At 60 feet long with a 72 inch circumference, this lightweight, black plastic tube is the largest Solar Tube available, 10 feet longer than any other solar bag on the market! Simply hold it open and run to fill with cool air, tie off the end, and move it into the sun. As the tube heats, the air expands, becomes less dense, and it begins to float.
Perfect for teaching:
- Solar energy
- Charles' Law.
Can be easily cut into three twenty foot tubes.
