You simpley just need to change the margin size. Go to your aboutme.css and in the .raindrop selector, add a margin-right of 20px or some other number of choice, making the code look like:

.raindrop {
  background: rgb(0, 162, 255);
  border-radius: 10px;
  width: 10px;
  height: 17px;
  animation: hai 5s infinite;
  display: inline-block;
  animation-direction: alternate;
  margin-right: 20px;
}

The page looks like this now:
