What you needCement
Avocado shell/skin and seed
Start by mixing 1 cup of cement. Follow the instructions on your cement packet.
Carefully cut an Avocado in half and remove the seed. This shell will become the mold for your cement. Spray the seed with a little spray oil but do not add it to the shell mold until the cement is nearly set.
Carefully pour or spoon your cement into the shell. You may need to use some Plasticine or play-dough to balance or level off the mold whilst the concrete sets.
Once it is nearly set insert the seed and apply a little pressure to form the seed hole for the finished design.
I sealed my avocado with PVA or white craft glue. These would make cute Christmas presents or hostess gifts.
