Bag of plastic milk bottle tops (Basingstoke RG21)

Clean plastic milk bottle tops, moat of them are transparent, the bag weighs about 140g so it's not that many but I'm loathe to throw them in the bin. The kerbside recycling accepts them if they're still on the bottles so I'm hoping somebody might want for an art project or something, or perhaps a church or charity is near me that is willing to collect or if not, can provide details on where I can drop them off?
