Balancing a Fork and Spoon on a Glass with a Match 

I just found your channel..and gotta say..where has this channel been all my life?!😆 Absolutely amazing to find a channel that has a host who carries true fascination, excitement and awe for physics, cosmology, and astronomy. While also teaching something clear and concise. Never change! Keep up the amazing work! 👏

Wait what how. That is awesome

Love your channel! You have a great way of making learning fun, like all the best teachers I remember from back in my school days. I hope your husband appreciates how lucky he is 😂 Plenty of great guys out there looking for a smart, badass, beautiful, science nerd to date! ☺️
