Always use gloves! 75 00:05:31,086 --> 00:05:33,768 Next we need a piece of aluminum foil. 76 00:05:33,803 --> 00:05:40,297 Rip it into small pieces and crumble them like this. 77 00:05:40,332 --> 00:05:42,436 Next we need a fire-proof base. 78 00:05:42,471 --> 00:05:46,205 The paper just gives the camera a better sight. 79 00:05:46,240 --> 00:05:49,225 And a heat resistant bowl. 80 00:05:49,260 --> 00:05:53,182 Put the aluminum foil crumbs into the bowl. 81 00:05:53,217 --> 00:05:59,217 Add 60 grams of NaOH. 82 00:05:59,252 --> 00:06:03,462 Add the threads of 3 'Coca-Cola' plastic bottles. 83 00:06:03,497 --> 00:06:10,094 Their threads are made from a different material than other brands. 84 00:06:10,129 --> 00:06:14,940 It consists of a carbon compound that will dissolve in our mixture. 85 00:06:14,975 --> 00:06:18,803 We could now pour boiling water on top. 86 00:06:18,838 --> 00:06:23,361 But as it's the vibration, the information we work with here, 87 00:06:23,396 --> 00:06:26,404 I decided to add some leaves and herbs. 88 00:06:26,439 --> 00:06:28,275 Some rose petals. 89 00:06:28,310 --> 00:06:32,788 Many others on the web experiment with herbs and plants. 90 00:06:32,823 --> 00:06:40,162 Some salvia leaves. 91 00:06:40,197 --> 00:06:45,149 Watercress currently populates our garden like weed. 92 00:06:45,184 --> 00:06:48,322 Perhaps this has a meaning. 93 00:06:48,357 --> 00:06:54,808 So I put it into the solution. 94 00:06:54,809 --> 00:06:59,577 And ivy. 95 00:06:59,941 --> 00:07:05,588 Into the solution. 96 00:07:06,329 --> 00:07:09,471 Remember: Put on gloves! 97 00:07:09,506 --> 00:07:14,483 They have to be waterproof and much stronger than these. 98 00:07:14,518 --> 00:07:19,213 Pour 1 liter of boiling water into the bowl. 99 00:07:19,248 --> 00:07:30,418 Take care not to inhale the vapor! 100 00:07:30,453 --> 00:07:33,833 Do this outside. 101 00:07:33,868 --> 00:07:37,444 And immediately put the lid on. 102 00:07:37,479 --> 00:07:41,844 Take care that as little vapor as possible is lost. 103 00:07:41,879 --> 00:07:47,658 The vapor must stay inside. 104 00:07:47,693 --> 00:07:53,030 Within the first minutes you can watch the aluminum foil dissolve. 105 00:07:53,065 --> 00:07:56,589 So be careful. 106 00:07:56,624 --> 00:08:02,765 After 3 hours it looks like this. 107 00:08:02,800 --> 00:08:07,805 Looks a bit disgusting, but mostly harmless™ ;-) 108 00:08:07,840 --> 00:08:10,791 Doesn't smell as bad as it looks 109 00:08:10,826 --> 00:08:15,770 but you shouldn't trust my nose. 110 00:08:15,805 --> 00:08:20,745 I poured it into this measuring jug, but it was too small. 111 00:08:20,780 --> 00:08:23,158 I should have poured it directly into the bottle 112 00:08:23,193 --> 00:08:29,286 if I'd had a cone. 113 00:08:35,622 --> 00:08:39,399 Pouring and pouring 114 00:08:40,104 --> 00:08:44,492 The bottle is not suited for food any more. 115 00:08:44,527 --> 00:08:53,539 Please mark appropriately and store safely. 116 00:08:53,730 --> 00:08:57,735 Mount a spray head from the cent shop. 117 00:08:57,770 --> 00:09:03,687 Use good gloves! This really burns the skin. 118 00:09:03,722 --> 00:09:09,117 And now screw tight. The vapors must stay inside. 119 00:09:09,152 --> 00:09:14,639 Our coating is ready for use. This is the chemical variant. 120 00:09:14,674 --> 00:09:19,289 Just holding the copper into the fire would have been much easier. 121 00:09:19,324 --> 00:09:23,826 But some of you perhaps like to do it this way. 122 00:09:23,861 --> 00:09:30,558 BTW, after a week my coating storage bottle looked like this. 123 00:09:30,593 --> 00:09:33,088 The thread totally disintegrated. 124 00:09:33,123 --> 00:09:37,199 Just like before when we mixed this solution. 125 00:09:37,234 --> 00:09:46,745 So don't store this in a Coca-Cola plastic bottle. 126 00:09:46,780 --> 00:09:52,386 We are still not done yet. Now comes the nano coating. 127 00:09:52,421 --> 00:09:56,295 The fire-and-water method would have been much easier. 128 00:09:56,330 --> 00:09:59,087 So, again dismantle an old cable 129 00:09:59,122 --> 00:10:02,254 and wrap the wires around a pencil 130 00:10:02,289 --> 00:10:08,294 to get a fine coil. 131 00:10:08,329 --> 00:10:15,939 An expensive wire also does it. 132 00:10:15,974 --> 00:10:22,932 Wrap around a marker in both rotations. 133 00:10:22,933 --> 00:10:26,601 Make sure that your coils will fit into the bottle 134 00:10:26,636 --> 00:10:31,736 in which the coating will take place. 135 00:10:32,796 --> 00:10:37,211 The copper coils go into a clean bottle. 136 00:10:37,246 --> 00:10:41,415 Taking them out again was difficult, 137 00:10:41,450 --> 00:10:45,104 so make sure you use a wide neck bottle. 138 00:10:45,139 --> 00:10:53,830 The narrow neck bottle I used here was no fun at all. 139 00:10:53,865 --> 00:10:59,359 Apply 1-2 sprays from the coating mixture. 140 00:10:59,394 --> 00:11:04,184 We don't need the solution but just the vapor. 141 00:11:04,219 --> 00:11:09,832 Just a nano-coating. 142 00:11:18,796 --> 00:11:23,040 Screw tight. 143 00:11:23,041 --> 00:11:25,826 Vapor now fills the inside 144 00:11:25,861 --> 00:11:31,713 which will coat the copper coils within the next 24 hours. 145 00:11:31,748 --> 00:11:36,182 First it looks like this. 146 00:11:36,217 --> 00:11:40,968 Place the bottle into the sunlight. 147 00:11:41,003 --> 00:11:44,752 After a few hours it looks like this. 148 00:11:44,787 --> 00:11:47,779 Turn it around occasionally. 149 00:11:47,814 --> 00:11:51,079 And remember, use a wide neck bottle, 150 00:11:51,114 --> 00:11:56,040 otherwise you will have a hard time getting the coils out. 151 00:11:56,041 --> 00:12:03,700 After a day it looks like this. Everything is coated in black. 152 00:12:03,701 --> 00:12:05,601 But we are still not done! 153 00:12:05,636 --> 00:12:10,413 We now have to decrease the potential. 154 00:12:10,448 --> 00:12:16,392 The African method is definitely a bit quicker, though. 155 00:12:16,427 --> 00:12:19,097 We need a galvanised fence. 156 00:12:19,132 --> 00:12:27,147 You get such a roll from the hardware store. 157 00:12:29,110 --> 00:12:34,021 Or you ask your neighbor for some pieces. 158 00:12:41,677 --> 00:12:45,273 It just needs to cover the bottom of a bowl. 159 00:12:45,308 --> 00:12:48,550 Ok, and you need a bowl. 160 00:12:48,585 --> 00:12:51,046 Apply some sprays of your coating. 161 00:12:51,081 --> 00:12:54,862 This will slow down the copper drying. 162 00:12:54,897 --> 00:13:01,328 Put the galvanised fence into the bowl. 163 00:13:01,363 --> 00:13:07,417 Use a pair of pliers to put the freshly coated coils on top. 164 00:13:07,452 --> 00:13:11,863 Don't touch them with your fingers! 165 00:13:11,898 --> 00:13:14,820 Loosely close the lid. 166 00:13:14,855 --> 00:13:19,679 The coated coils will dry within the next 1-2 days. 167 00:13:19,714 --> 00:13:24,242 This is a wider bowl, so you can see more. 168 00:13:24,277 --> 00:13:29,098 And every few hours we decrease the potential in each coil. 169 00:13:29,133 --> 00:13:37,539 That means, a current flows here. While we measure it, it goes down to zero. 170 00:13:37,574 --> 00:13:51,321 Switch a multimeter to DC and mV, hold (-) to zinc, (+) to copper. 171 00:13:51,356 --> 00:14:04,439 Repeat this every few hours with every coil. Loosely close the lid again. 172 00:14:04,474 --> 00:14:12,639 With every measure, millions of nano graphene layers build up on the coils. 173 00:14:12,674 --> 00:14:19,789 At first the scale will go down to zero. (If not, it's ok, too.) 174 00:14:19,824 --> 00:14:28,883 The more often you measure, the more the scale will start to wobble. 175 00:14:28,918 --> 00:14:34,204 So if the scale goes down to zero, hold on! It may go up again. 176 00:14:34,239 --> 00:14:39,196 It may go up, or even go down to negative. 177 00:14:40,683 --> 00:14:44,329 The more often you measure, the stronger the wobble. 178 00:14:44,364 --> 00:14:54,781 Up - down - up - down - and don't stop measuring at zero. 179 00:14:56,659 --> 00:15:02,334 Negative values are ok, too. All we want is the wobble. 180 00:15:02,369 --> 00:15:07,756 With every wobble, millions of nano graphene layers build up on the coils. 181 00:15:07,791 --> 00:15:14,583 And that's what we want to achieve. 182 00:15:20,957 --> 00:15:25,324 As I said, even negative values are ok. 183 00:15:25,359 --> 00:15:30,106 And again up - down - up - down... 184 00:15:39,441 --> 00:15:46,416 And then we measure the next coil. And so on. 185 00:15:46,451 --> 00:15:54,400 For the next 1-2 days you repeat this with every coil, every few hours. 186 00:15:54,435 --> 00:16:01,083 In total that's about 10-12 measures per coil. 187 00:16:01,118 --> 00:16:06,735 Always loosely close the lid after each measuring turn. 188 00:16:06,770 --> 00:16:11,919 Repeat the measures until the current does not drop down to zero 189 00:16:11,954 --> 00:16:17,185 but stays up. No matter which value it reads. 190 00:16:17,220 --> 00:16:22,431 Here it's not about output, but pure information. 191 00:16:22,466 --> 00:16:30,994 As we know, information does not have to be strong or loud. 192 00:16:31,329 --> 00:16:35,063 This is how the copper coils look like in the end. 193 00:16:35,098 --> 00:16:37,649 Don't touch them with bare hands! 194 00:16:37,684 --> 00:16:43,432 Always touch nano coatings with gloves only! 195 00:16:43,433 --> 00:16:46,618 That's it! That was the sophisticated way 196 00:16:46,653 --> 00:16:49,476 to nano coat copper coils. 197 00:16:49,511 --> 00:16:53,443 In the next films we show you what to do with it. 198 00:16:53,920 --> 00:16:55,141 I am Andi. 199 00:16:55,176 --> 00:16:59,178 Thanks for your time, your patience and all the helpful hints! 200 00:16:59,213 --> 00:17:05,611 I wish you the best in life and happy crafting!
