Breakable without causing a bloodbath!
Breakable without causing a bloodbath!
(OP)
Hi All,
I'm trying to build a prototype box that has a clear, breakable front. It's going to be approx the size of a shoe box sitting on its long side.
The trouble I'm having is tracking down a plastic that is breakable but won't shatter everywhere or leave sharp edges (the owner is going to need to be able to reach in through the smashed hole). The only alternative I can think of is somehow scoring the plastic so that it naturally breaks along set lines, but I'd like to avoid the visible lines that this would result in.
I don't suppose anyone has any suggestions do they, I feel like I have a great idea but am falling at this last hurdle!
Any help at all would be much appreciated.

KENAT,
Have you reminded yourself of FAQ731-376: Eng-Tips.com Forum Policies recently, or taken a look at posting policies: http://eng-tips.com/market.cfm?
What is Engineering anyway: FAQ1088-1484: In layman terms, what is "engineering"?

Let me know if you would like help in detail designing this.

Sorry for the slow reply, have been back up in sunny old North Yorkshire for a few days without access to t'internet.
Thanks for all the suggestions, I had no idea there would be so many people offering advice. Warms the cockles.
I am basically trying to recreate an 'In case of emergency break glass' box but one that could be used without immenent death justifying lacerated fingers! Because of this, there certainly does need to be the satisfaction involved in actually smashing the thing, and I positively don't want it to be reusable because that removes the incentive not to open the box!
The resin and the PET film seem like the most suitable options, so I'll be investigating those further when I get back down to the big smoke next week.
Thanks again everyone for your interest, and I'll keep you posted if and when a suitable solution is confirmed!
p.s. that's certainly not to say I'm not open to more ideas!

If that doesn't work you could put a stress concentration in the corners that makes it split. Your hand never goes through the hole full of sharp edges.
Don't discount glass. Car windows have this same issue where you don't want to get decapitated after going through the windshield.

Suggest you have a look at BS5839. It might have to be glass for some reason:
