What's your problem?  Deletion works ok:

irb(main):020:0* a=Item.new "a"
=> #<Item:0x10192810 @body="a">
irb(main):021:0> a.add
=> [#<Item:0x10192810 @body="a">]
irb(main):022:0> Item.find_recent
=> [#<Item:0x10192810 @body="a">]
irb(main):023:0> a.del
=> []
irb(main):024:0> Item.find_recent
=> []
irb(main):025:0>

Kind regards
