Brief
Using magnets and nail polish in an attempt to gain a sixth sense.
Writeup
The reasoning and conclusion can be found on my blog writeup.
Components
- 50 x Neodymium Disc Magnets (2mm x 1mm) = £2.90
- Nail polish = ~£4.50
- Nail polish remover (Acetone) = ~£2
Process
- Group and place the required sets of magnets on a flat surface. I went for 4 groups of 3 magnets in a line so I could line the left and right edges of my right hand ring and little fingers.
- Paint one nail with nail polish.
- Carefully lift and position a group of magnets on still wet nail.
- When positioning the second set of magnets be careful not to disturb the previously set group by getting to close with the current set of magnets.
- If you make a mistake use the acetone to remove the nail polish.
- When the nail polish has dried apply another layer or two to secure the magnets in place.
- Once the first nail has completely dried move onto the next one. If you don't wait you risk detaching all the magnets and having to start over.
