i.What makes it really unique is it actually displays different gravity than it is on Earth.
j.The sliders of Moondrop are precisely made to free fall in the correct speed that imitates either Lunar or Mars gravity.
 
Moondrop Lunar: The slider is made from Aerospace grade aluminium. The distance of falling slider is 38 mm. The time for slider to fall that distance is 0,22 s which is the same as for any object dropped on the moon and falling it's first 38 mm.
 
Moondrop Mars: The slider is made from pure copper. The distance of falling slider is 38 mm. The time for slider to fall that distance is 0,13 s which is the same as for any object dropped on the Mars and falling it's first 38 mm.
 
Moondrop Earth: Turn any of Moondrops into Earth version by removing the magnets and compare the gravity between all three.
 
Why We Call It "Moondrop" ?
Moondrop is to imitate the Lunar gravity. It is precisely calculated so vertically falling slider moves at similar speed like you were dropping any object on the lunar surface. The gravity on the Moon is 1,6 m/s² which is only about 1/6th of that on Earth. Since there is vacuum on the moon there is also no air resistance - this makes any object no matter how big free fall in the same speed. How cool is that?

Find the best size

When comparing your measurements to those listed on the site, make sure to check if the fabric is stretchy or not. If it is, it can stretch an inch or more.

  • Bust: Wrap the measuring tape loosely around the fullest part of your bust to ensure a comfortable fit.
  • Waist: Measure the narrowest part of your natural waist, holding the measuring tape loose enough to fit comfortably.
  • Hips: Drape the measuring tape around the widest part of your hips, resting the tape comfortably against your body.
  • Length: For tops and dresses, measure from the top of your shoulder to the hem. For strapless dresses, measure from the highest part of the neckline to the hem. For pants and skirts, measure from the top of the waist to the hem.
  • Sleeve: With your arm outstretched, measure from the base of your neck to the end of the sleeve hem to determine where the sleeve length will fall on you.
