Walk away from your own shadow

This was easier to do back when TVs had fluorescent screens but if you can get your hands on an old set, Rob shows you how to walk away from your own shadow.

[@Surannhealz]

This explains why you can get a 50" 4K TV for $250....because they left out the ability to walk away from your own shadow. It was a very expensive feature.

[@89horizon]

It would be very frustrating for a vampire though since they don't cast reflections or shadows. No TV will work so they'd paying all that extra money for nothing then. :P

[@I_WANT_MY_SLAW]

No, it's because they have ads built directly into the televisions. And since they are smart, they also track what you watch, so they can give you targeted ads based on your viewing preferences. It's pretty scary that we live in times where you have to agree to a user agreement on a TV you bought, and own, in order to use it. And the company "technically" has the right to turn your TV off, and stop providing service for it. Even though it's your property.

[@AlwaysOnForever]

@@I_WANT_MY_SLAW Yeah, i already pget used to it. You are forced to agree with google to be a "normal human" and the could force you to agree everything and you can't deny it. Probably they are anilizing my comments but i don't care anymore, bet there are a ton of people that are worse than me

[@feelinghealingfrequences7179]

and the smart tv watches you and records you and tracks what your eyes look at and for how long and how often

[@I_WANT_MY_SLAW]

@@feelinghealingfrequences7179 no it doesn't watch you. There are no cameras in them. Yet.

[@SavageMontreal]

Thank you Rob and thank you Deane for making these clips available. I loved this show as a kid and have many fond memories of it. Even now, approaching 37 years of age, I still find these videos very educational and appreciate the clear and concise manner in which you two are able to explain the science behind everyday phenomena. I'm very happy to be able to watch these again, and hope that a whole new generation of viewers is able to reap the benefits of your knowledge. Thanks again.

[@CuriosityShow]

Many thanks.Curiosity Show featured Dr Rob Morrison and Dr Deane Hutton. A science TV series for children, it was broadcast nationally in Australia (where it was produced in Adelaide) and to 14 countries overseas and dubbed into German for European audiences. It won the Prix Jeunesse International in 1984, the top award in the world for children's TV. Lots more segments at kzbin.info where archived segments are uploaded every week

Another thing you can do with an old CRT TV is "Newton's Bells" made from two soda cans, one pull-tab, a pencil, and some aluminum foil. The static charge on the screen that happens right after you turn it off can power the bell.

There is a useful technique for preserving the dark adaptation of your vision while still be able to see at all times. It seems rather obvious, but surprisingly few people seem to be aware of it. It is simply to keep one eye closed to preserve its dark adaptation while using your other eye to see. Then when you need dark-adapted vision, you can open the closed eye and close the open eye (to avoid distractions, and to let it start dark adapting).
