Here's two horrible, nailbiting brainstorming puzzles ! The clues on the left will give you a 5-letter word. You can remove a letter from this word and unscramble the remainder into a new 4-letter word. Put the discarded letter and the new 4-letter word in the columns provided. Next you should be able to add a different letter to the 4-letter word and make another word by moving them around. Put the added letter and the new 5-letter word in the columns provided.

If done correctly, the takeaway letter column and the added letter column should read downwards to show words associated with Amateur Rocketry. Clear as mud ? Good luck !!
