I was taught to apply it, change into your speedo’s, use your goggles of course( you don’t want it in your eyes), get down in swimmers position, and start doing the breast stroke. You’ll want to have enough forward momentum to get yourself across the room. That’s one lap. Turn around, and repeat the process..... it is also important to remember to work quickly, you don’t want it drying up before you have a chance to cover the entire room in ‘laps’. But worry not, if you aren’t swimming fast enough, just have your helper/coach reapply more dye...... AND REMEMBER...... CHARGE LARGE MARGE.........
