スイカもカボチャも水に浮く。

Watermelons and pumpkins float in water.

お酒を飲んだら、宙に浮いているようなフワフワした感じになった。

After drinking, I felt light and floaty, as if I were floating in the air.

こんなとこでおっさん二人がおままごとをしてたら、完全に浮くだろ！

If we, two middle-aged guys, were playing house in a place like this, we'd totally stand out!

良かったら、お茶でもしない？おごるよ。ほしかったサングラスがセール中だったもんで、お金が浮いたんだよね。

Would you like to have some tea? I'll treat you. I got some money to spare because the sunglasses I wanted were on sale.
