Making Basic Antennae

I will just focus on making a basic latex antennae shape, non-motorised. You'll find that using solid latex, it is rubbery, flexible and bouncy, so will move quite nicely with the jerky movements of walking.

First you need to create the antennae shape, using plasticine or similar.

This is the general shape we were going for, however this is actually one of the finished motorised antennae.

After you have made the plasticine shape, you need to make the reverse mould, by using Plaster of Paris. However you need to do half of the mould at each time.

In an ice-cream container, fill to a decent level (just under halfway or another appropriate level, you only really need it to be deep enough to capture the mould shape), and press the mould into it, so half of it is cast, you will also probably need to use a straw or something to make a 'hole' that will allow you to pour the latex into the mould later. Leave to set.

Repeat for the other side. You now have moulds for both of them

It's now easy to make a solid latex antennae, it is important to consider how you are attaching the antennae (we used a headband built into a wig), as you will need to build in connectors to the mould.
