So I was changing my fork seals yesterday and needed a funnel to pour my 17.62 ounces of 15W fork oil into their tubes without making a huge mess. The two funnels I have are slimed with oil and I didn't want to mix the fluids or spend 10 minutes scrubbing one of them and making sure it was completely dried out before I poured fork oil in it.
While searching the house for a suitable replacement I came across my wife's pastry bags that she uses for decorating cakes and such - and they worked perfect! They're cheap too. $4.99 for a box of twenty. No more washing the funnels for me.
Thanks for the tip. That's just icing on the cake!
