🔴 What Is Islam? ⚠️ 🔴 Islam is not just another religion. 🔵 It is the same message preached by Moses, Jesus and Abraham. 🔴 Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God. 🔵 It reminds us that since God created us, no one should be worshipped except God alone. 🔴 It also teaches that God is nothing like a human being or like anything that we can imagine. 🌍 The concept of God is summarized in the Quran as: 📖 { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4)[4] 📚 🔴 Becoming a Muslim is not turning your back to Jesus. 🔵 Rather it’s going back to the original teachings of Jesus and obeying him.

I discovered this show as a 41 year old American man and I love these videos. We had a show like this called Mr. Wizard, which was similar. If this show would have been on after school in the 80s, I would have watched this, no doubt.

There are other factors besides the explanation: 1) When cutting just paper, the knife is held at an angle, so the blade/paper interface (contact area) is reduced to a single point. This focuses the entire force on a single paper fiber. On the potato, the interface is wider, even on top, since the potato is not 100% hard. It gives in a bit, expanding the interface to a short line. Further down, the blade/paper interface is literally 2-3 inches wide. 2) When cutting just paper, the blade moves across with respect to the cutting point 3 times, like a saw @0:17. No such motion on the potato: it's more "pressing down", not "sawing through"

I agree with the difference you pointed out between the presenter cutting paper along the crease at an angle and cutting a potato by pressing straight down. He wasn't comparing like with like. I went on to try cutting newspaper the "potato" way using a long carving knife with a straight blade, abruptly tapering to a rounded end. I laid the straight edge of the blade between the folded halves into the crease so the edge was in contact with the crease all along its length, not just at one point, then pulling hard on both the paper and the blade in opposite directions. A surprising amount of force was needed to cut newspaper like that. And impossible when I tried it with an ordinary sheet of office paper. Certainly more force than was needed to cut a potato with the same knife, with and without paper. Interesting though the effect is, I think it only demonstrates the different cutting properties of paper and potato.

Love that you weren't scared to suggest kids try this one. Helping your parents out in the kitchen is an invaluable skill to learn as a child.

You say Potato, I say Po-tah-toh, Potato, Po-tah-toh, lets chop the whole thing off.

I had a pair of black nitrile gloves on one day, and cut my hand with a Stanley knife. The glove was unharmed and didn’t think anything of it (apart from that it hurt). When I took the glove off later, it was filled with blood. Skin cut, but the glove was unscathed.

0:51 "Tomorrow: Mad Max color special" 😁

August 1, 1985 Mad Max Color Special - wow they really make these look authentic 😊

Doesn't the fact that the knife cuts through the potato mean that there's more force on the inside and not equal force?

Kids of 2024.... What is a newspaper... What is a sharp knife .... What is a potato? Parent... You my dear are a potato.

Clips like this make me wish I had kids so I could blow their minds with this as you have mine

I recently banged into a corner, cutting my shin but not my trousers. And your experience is why every can lid should be put down inside the can, at the bottom, with other recyclables packed around to keep the lid from falling out before the can is removed from the bag.

The paper says "MAD MAX COLOR SPECIAL". Australians gonna austral.

That was such a good explanation.

The wanted photo on the newspaper looks suspiciously like one of the hosts lol.

If potato is applying the opposite force then why is it being cut

Nice have i heard that song " curiosity" before?seems like deja vu

Oh wow Rob basically made sharp paper knife 😮

What a great way to cut potatoes without having to touch them with your fingers.

It reminds me as a kid watching Mr. WIZARD. Enjoyed the video.

you'll have to do it with The Advertiser or another paper though

Consider me educated and amazed now. That was great. :D

Thanks. Curiosity Show was a national science program featuring Dr Rob Morrison and Dr Deane Hutton. It was made in Adelaide, South Australia and screened nationally in Australia as well as in Europe, Asia and Australasia (14 countries and dubbed in German for Europe) from 1972-1990. Deane and Rob intentionally used everyday items around the house (like old rusty cans) so that people could repeat the demonstrations with materials they had to hand. In 1984 Curiosity Show won the Prix Jeunesse International, the world's top award for TV programs for young people. Rob and Deane are steadily uploading segments at kzread.info Why not subscribe?

Okay, this is just witchcraft.

You wanted to show level of force yet you used newspaper which is equally teareble in 4 and 8 layers.

Whenever I get a quesadilla from Taco Bell they cut it into four pieces after its already in the paper sleeve and I’ve always wondered how it was possible to not ruin the sleeve. I thought Taco Bell just had special paper that somehow wouldn’t get cut but now I know its just a physics trick

Great trick. And also as paper is actually very difficult to cut as its fibrous.

I was just watching The 10 Morning Show where Rob and Dean did the egg in the bottle and the potato . the host was being highly annoying and to Rob's credit he told him to go away I thought that was classic, the host just wouldn't shut up
