Nuts and bolts - Clear ice bucket and tea lights I use.

I have included links in this post, to these products in order to make it easy for you to access and review them.  If you make a purchase from Amzon.com I will receive a small portion.

I love thisProdyne Iceberg Party Tub -It is strong. Has a great thickness to the material. I think the the design is versatile to use at weddings and at birthdays.   They nest together for easy storage and portability.  I use these for chilling wine and beer.  It will hold about 5 bottles of wine or about 8-10 bottles of beer.   You just need to pay attention how far you fill it with ice.  The handle cut outs are below the top of the Prodyne Iceberg Party Tub ;so if you don't pay attention ice will fall out of them.

When you drop in Submersible LED Lights the edges and shape make the light reflect in the water with a cool effect.  It  adds a nice touch for weddings since it is usually dark.  

One trick I discovered is using the tea lights in the large tubs I use for beer and sodas at night.   When you drop in the lights it makes it so much easier to see what's in there.  Makes a huge difference for back yard parties.   I also drop them into containers with dry ice fog to give a great effect.
