Bounce on a trampoline, taking it in turns to be in the middle. All the people around the edge should bounce and shout words of prayer for the person, for example, things they want God to bring in their life: e.g. health, good friends, help with school, joy, peace.
Alternatively, you could play ‘Crack the egg’, where one person curls up in a ball in the centre and everyone else tries to make them unroll by bouncing. When the ‘egg’ is ‘cracked’, pause for a moment and each pray a blessing of good things from God on that person, before someone else has a turn.
Younger children could think of one great thing and pray that for everyone. Pray the prayer then play ‘crack the egg’.
