In this jsfiddle you'll see that there's enough space for a third block under the second block. Is it possible to push the third block under the second block so that there's only two rows?

.list {

flex-flow: row wrap;
width: 20rem;
}
.item {

width: 5rem;
background-color: blue;
margin: .2rem;
}
.item:nth-child(1) {
height: 10rem;
width: 10rem;
}
<div class="list">
<div class="item"></div>
