Something pleasant, instead of the HORRID HEAT :~)
Amazon has Butterfly Kits on sale for $7.97 (shipping is $3.11). The "list price" for these is $24.99. You get a collapsible habitat, feeder and instructions, along with a voucher (to mail in with $5.00 handling fee) for 5 larvae and special food.
I have no idea if this is a good deal or not...just thought it was cute and it (momentarily) took my mind off the heat.
