Introduction

Pen stand is a simple toy, which helps us observe magnetism and understand magnetic levitation. Here, its enjoyment is increased further by placing a coloured fan on top to aid its spinning!

Video Overview

    • Handle the scissors with care.

    • Make sure you don't pinch yourself with the cutting pliers.

    • Be careful while bending the spoke as you could hurt your fingers and hands while bending it.Do not try to bend it with your teeth.

  1. You need to make 2 bends in the spoke assembly. Although possible and a lot of fun with bare hands, using cutting pliers to make the bends would be a lot easier. After about 1 cm from the pointed end of the first bend, bend the spoke at right angles, as shown in the second picture. The result should resemble a lamp post.

  2. At the bottom of your spoke is an  'L'  bend.Halfway down the length of the bend, bend again by 90⁰, on the same parallel plane  as the previous bend. This final bend completes your stand.

  3. Take a piece of tape, and stick the spoke on the CD such that the last bend creates the base and the first bend forms the top, like a lamp post. Make sure that the only surface directly under the lamp post is that of the CD itself.

  4. Place one ring magnet on the top or the underside of the bend at the top of the stand.
    • Place one ring magnet on the top or the underside of the bend at the top of the stand.

  5. Take a piece of paper and fold it 4-5 times. Place the paper at the end of the pen and then slide a ring magnet at the end of the pen. The paper serves as packing and your magnet should stay firmly in position now. You may need to increase/decrease the number of folds of the paper, for the magnet to fit firmly.

  6. Remove the pen cap and place the pen on the CD directly under the magnet on the top. Your pen should now be standing on its own; you now have a vertically levitating pen stand! You can give the pen a bit of a twirl, and it should spin for quite some time. Remove the pen cap and place the pen on the CD directly under the magnet on the top.

  7. Cut a piece of cardboard exactly to the shape and size of the given colour-square sticker. Stick the colour-square to your cardboard piece. Cut and fold the colour-square, as indicated by the dotted and solid line. Put the piece of double-sided tape under the colour-square and stick this to the top of the pen

    • Cut and fold the colour-square, as indicated by the dotted and solid line.

    • Put the piece of double-sided tape under the colour-square and stick this to the top of the pen

    • Ensure that the pen continues to levitate and that the colour-square doesn't interfere with the rotation of the pen by hitting the stand

    • Place the pen stand under a ceiling fan, turned on to its maximum speed, and enjoy the spinning levitating pen stand with a Newton disc!

    • If a fan is unavailable, or if there is no electricity, you may blow from the top as well to have your spinning pen!

    • Magnet exhibits angular orientation - The top bend is not parallel to the ground.

    • Magnets repelling each other - Check for the orientation of the magnets and arrange, such that they attract each other.

    • Pen is not steady and repeatedly falls - There is a lot of gap between the magnets.Note: If your magnet is placed on the underside of the bend,then place it on top of the bend.

    • Pen is getting attached to the magnet on the bend - There is very little gap between the magnets.Note: If your magnet is placed on the underside of the bend,then place it on the top of the bend.

    • The position of the pen is not steady - Magnet on the pen is not placed firmly enough.

    • Stand is not steady - Stand is not taped firmly enough to the CD.

    • Colour-square doesn't fit correctly on the pen - Colour-square is not folded or cut correctly.

    • Colour-square hits the stand, thereby interfering with the spin - Folds on the colour-square are too big.

  8. Variation 1: Change magnets. Variation 2: Replace the pen with different materials, for example, a string tied to a magnet. Variation 3: Use multiple pens.
    • Variation 1: Change magnets.

    • Variation 2: Replace the pen with different materials, for example, a string tied to a magnet.

    • Variation 3: Use multiple pens.

    • Variation 4 :Change the base.
