Bubble Lift

You blow a bubble around any solid, granular, or liquid
object that weighs 500 pounds or less, causing it to float
4 feet off the ground. No matter what the contents of the
bubble are, the bubble weighs 10 pounds and can be pushed
using an action. Strong winds or effects that would push
a creature also push the bubble. The bubble always floats
at least 4 feet off the ground, and descends from a fall at a
speed of 10 feet per round.

As an action, a creature can pierce the outside of the
bubble, causing it to pop and releasing its contents.

At Higher Levels. When you cast this spell using a spell
slot of 2nd level or higher, you can increase the weight the
bubble can lift by 500 pounds for each slot level above 1st.
