Summarize:

This method of removing acrylic nails is not recommended by nail professionals. Using floss to remove your fake nails can result in pulling off part of your natural nail, which can be painful and possibly lead to an infection. These are widely available and they are perfect for removing fake nails. To make the process even easier, you may want to choose a brand that is meant for flossing between tightly-spaced teeth, such as Glide. If you don't have or don't want to buy flosser sticks, then you may also use regular floss. However, you might need a friend to help you since you won't be able to keep the floss taut with only 1 hand.
Be aware that this technique may damage your natural nails. Purchase dental flossers that are on a stick.
