Not only are Earth heads a great photo opportunity (you may have spotted them in the media following the Anti-Trump protests), they also make you much easier to spot in a crowd.
Before you start, make sure you've left yourself plenty of time as they'll take several days to dry.
Get a beach ball or big round balloon – though adapt size accordingly if you're making one for a child. As you can see, Alfie here needed a slightly smaller balloon!
Use scrap newspaper and a mix of PVA glue and water to coat the balloon or ball, leaving a head sized hole around the bottom so you can easily slip your (or your child's) head into it.
Leave to dry for half a day, then add another coat. Repeat with 4 or 5 layers, leaving to dry between each layer. Finish with a 24 hour drying period.
Once you’ve left the last layer to dry for 24 hours, gently deflate the balloon or ball and remove through the hole you've left for the neck.
With a pair of scissors, carefully tidy up the neck hole. Mark with pencil where you'd like your eyes and mouth. Then sketch out the continents.
Cut out the eye holes, gather your paints and start colouring – don’t forget the sad mouth and eyebrows!
Once your paint is dry, you're protest-ready. We'd love to see your efforts, so send us any action shots on social media and tag @friends_earth
