Talk: Watch the bubbles rising and think about the sight of Jesus ascending and what that might have meant for the disciples. What might they have been thinking/ feeling? What does it feel like to wait for something, as the disciples had been told to go and wait for the Holy Spirit to come?
Pray: Think about situations where you or people you know are waiting for something to happen.
As you drop the tablet into the liquid and see the bubbles ascending, pray that God will take the worries and stresses of waiting away and that they will feel God's presence with them as they wait.
