Practical Engineering | How to Super-Size the Eclipse - Sun Funnel @PracticalEngineeringChannel | Uploaded August 2017 | Updated October 2024, 5 days ago.
If you've got a telescope, give the crowd a show next week. Make the eclipse bigger! Eclipse glasses are okay, but the sun is only as big as your thumbnail at arms length. That's not very big. I need something to impress some kindergartners! Hopefully the sun funnel can do it.
