Towards the back of the machine normally counts as up for upwards-facing sockets, unless it’s a case with feet on the side, in which case it’ll be away from those feet so the sockets would be the right way up if it were sideways and on the alternative feet.
Starburst is the brand. The product you’re thinking of is Starburst Fruity Chews (formerly known as Opal Fruits), but they make other products. They used to make the best jelly beans, under the name Starburst Joosters, but they got discontinued. It looks like either they’re back, but under the much more boring name Starburst Jellybeans, or they’ve decided to make different jelly beans so given them a new name. Either way, they’re still not available in the UK, and people seem to be complaining that the recipe changed recently to make them worse, so the hope this thread gave me has been thoroughly dashed.
