Well certainly any bystanders speared on the extended arms will slow down the thief...
Probably not a lot of room left in that briefcase for your average contents....Would love to see the reaction if the device failed to activate until the thief jumped into his waiting get-away vehicle....Quote:

Now that I like and would be useful. Like to see that up close and how it's made.
Per the woman in the GIF: when you see windows covered up by black garbage bags, this must be what's really going on inside.
I used to have a collapsible stainless drinking cup. About a 1/2 inch tall when collapsed and held around 8 ounces when extended.Quote:

Very doable
The handle was spring loaded to retract when the telescopic radials extended.Quote:

The collapsible staff functions the same way as a paper yo-yo, only made from a strip of metal and biased towards remaining extended.
If anyone would like to investigate further, they go for $5-7 on ebay.
7 bucks, not bad! Let me know if you see a cheap one that doesn't take a month or two to ship from China; it looks like it's good for probably at least 45 minutes of entertainment before my son breaks it.
