Step 2 Make moulds

You need food-grade silicon if you are going to eat whatever you make. For the mould casing, I used an old tin lid. Anything will do, as long as it it not porous - don't use a match box lid like I did the first time.

First, work out how much silicone you'll need. You'll need enough to almost cover your lego pieces. This takes trial and error, if you do it the way I did.  A better way is to measure the volume of your vessel including the lego - I guess you could use water and then measure how much it took. Add a few extra mls for what you won't be able to scrape out of the silicone mixing container. 

Measure your silicone - you have to get this right. Use a syringe or accurate measure. Pinkysil is a 1:1 mix, and you have to get it exact or your silicone doesn't cure properly. So if your final volume is 25 ml, you need 13ml of each part (leaving only 1ml spare - so mix 15ml of each instead). Mix thoroughly and pour it in, then insert the lego.
