Does anyone know what number plastics work?

I do not remember these but love the idea will have to try it with my 3 year old I think she would love making them

Hi – can anyone recommend the specific plastic they use? I want to do this with my pre-schoolers for Father’s Day/Special Person and be sustainable by reusing plastic packaging. My attempts are shrinking a bit but also going white. I used the tray housing mini muffins from Safeway. Maybe it’s the wrong plastic?

They look really cool and funky.

I remember doing this in the early 90’s, I am definitely keen to give this ago

Oh how I remember doing this to chip packets, brings back lots of happy memories.

OMG, these take me back. I also remember how we used to melt down twisties and chip wrappers in the oven!

Has anyone tried this as i have tried most plastic containers and they melted more than shrunk. I found it very hard to get #6 category as category 6 is Polystyrene (PS)
Expanded Polystyrene
(EPS)
Yogurt pots, plastic cutlery, hot drink cups, take-away containers
Rigid and brittle, clear or glassy-
looking, lightweight and foam-like
Clothes pegs, coat hangers

we used to put crisp packets in the oven and they would shrink down!

Oh I remember shinkies! They were so much fun! I’m going to have to try these. What sort of plastic though? Just the containers strawberries etc come in?

  They were fun and they were so popular and they were everywhere!

I loved making shrinkies when I was a child and this tutorial makes this method seem just so super easy. Thanks for the easy to follow step by step ‘shrinkies’ tutorial. The shrinkies in the video look so colourful and cute. Will have to be creative and try our hands at these shrinkies.

Aw, I didn’t realize you could make these with just the clear container from fruit !
My 7yr old would love to do this !!

I remember being fascinated by them when I was a kid, colouring it in then watching it shrink in the oven. Very cool!

I remember these and I didn’t know they were so easy to make.

I haven’t seen these before but they look so cute!
