I wanted to pique my six-year-old’s interest in science with an exciting experiment. She knew well already, how the magnets attract each other, so we built something interesting to experience they can repel each other as well. This flying rose is great for experimenting with children, but it looks quiet cool so it can be a special decoration or a great gift for example for Mother’s day or Valentine’s day. If you poke it with your finger it sways like a nodding dog.
Two facing magnets are keeping the rose in the air and it is balanced by four fishing lines.
- two ringmagnet (60 x 10 mm, adhesive force: 6 kg)
- a round plastic flowerpot (diameter: 65 mm, height: 65 mm)
- a rose in plastic pot (diamter max: 60 mm, height max 50 mm)
- a trivet or a flat dish (diameter: 175 mm)
- fishing line (diameter: 0,35 mm)
- adhesive tape
- powerful universal glue
- felt, perls, ribbon for decoration
The plastic flowerpot and the rose shouldn’t weigh much.
First cut 4 long (15 cm) pieces from the fishing line. Mark four points an equal distance on the flowerpot with a protractor or something that has a right angle. These are the places of the fishing lines.
Affix well the fishing lines to the designated locations with the tape. Be careful, they will want to escape. Hide the tapes with some felt and decorate it with the ribbon or other lightweight stuff.
Measure out the length of the fishing line. If they are too short, the rose will fly too low, but if they are too long, the rose will not be balanced and it will fall. In my case 5,5 cm long fishing line are holding the rose stable, but the stronger your magnet is the higher the rose can fly, maybe you have to experiment a bit. You can put some perls on the fishing line as well if you want.
Affix well the fishing lines on the trivet or flat dish an equal distance.
Affix the magnet in the bottom of the plastis flowerpot and in the middle of the trivet, the same poles should face each other.
Check how the flower pot flies and correct the length of the fishing lines if neccessary.
Put the rose in the pot and check it again. When it flies perfect, hide the trivet with a felt.
Congratulation, your flying rose is ready!!!
